Overview

Use this page to understand where Technical Wiki parts fit in a build, what supporting parts matter, and which buying path best matches the vehicle's use case.

The best purchase usually comes from matching the part to the vehicle, build goal, install constraints, maintenance needs, and realistic performance expectations instead of shopping by hype alone.

Read the quick facts, compare the shop paths, then move into the catalog with the terms, risks, and support items that matter for your setup.

Fitment First Support Parts Matter Build Goal Driven Install Notes Count Maintenance Ready Catalog Path Clear

Best mindset for this page

Start with the job the part needs to do, the system around it, and the trade-offs your vehicle can accept. The right answer changes between street, track, race, show, tow, and custom builds.

Fast Reference

Quick Facts

Short blocks that help users understand the system quickly before diving into deeper detail.

Sound is only part of the story

A good exhaust changes flow, pressure behavior, heat, weight, and packaging. Noise alone is not performance.

Pipe size is not one-direction better

Bigger tubing can help high-flow combinations, but too much size can hurt velocity, response, and overall balance on mild builds.

Headers and manifolds change power shape

Runner length, collector design, merge quality, and manifold style all influence where the engine gains or loses.

Turbo exhaust backpressure matters

Downpipes, turbine outlet flow, wastegate routing, and hot-side packaging strongly affect spool, EGT, and overall efficiency.

Heat control protects the rest of the car

Wrap, shields, blankets, coatings, and routing decisions matter because exhaust heat attacks wiring, hoses, plastics, floors, and intake temps.

Fabrication parts make or break custom systems

V-bands, flanges, flex joints, hangers, and bungs decide whether a custom exhaust is serviceable and reliable.

Public Education

What These Parts Do

This is one of the best sales upgrades you can make. Most public buyers do not need more hype. They need clear explanations of what a part actually changes on the vehicle and why it matters.

What these parts actually do

Exhaust parts control how hot gases leave the engine or turbo system. That affects scavenging, backpressure, spool, sound, weight, temperature, and service access.

Where the gain shows up

Some upgrades improve peak power, some sharpen response, and some mainly improve consistency by lowering heat and restriction over repeated pulls or laps.

What sound changes mean

Tone comes from pipe diameter, muffler design, resonators, crossover strategy, catalyst choice, and engine firing behavior. Louder does not automatically mean faster.

What these parts do not fix

Exhaust upgrades do not solve bad tuning, poor fuel supply, weak turbo sizing, or mechanical engine issues by themselves.

What to pair with them

Headers often want tuning. Turbo parts often want wideband support, heat control, and engine-management changes. Custom systems often need sensors, bungs, and fabrication hardware.

Who really needs them

Street, race, off-road, turbo, and custom builders all buy exhaust parts for different reasons. The right answer depends on the build goal, not just the loudest option.

Why this converts

The public buys faster when the page explains the function, the gain, the limit, and the correct support parts in plain language. This lowers decision fatigue and reduces returns caused by wrong expectations.

Expectation Setting

Expected Performance Change

This section keeps the page honest. It teaches users that not every good part adds headline power, but many parts make the vehicle faster, stronger, more repeatable, or easier to trust.

Performance Goal What to Tell the Customer Sales / Buyer Note
Horsepower Flow improvements can add power when the stock system is restrictive, especially on boosted or high-rpm engines. Be honest that gains depend on engine combination, pipe size, and calibration.
Torque curve and response Headers, manifolds, collector design, and tubing size can shift where the engine feels stronger. This matters as much as peak number for street and road-course cars.
Turbo spool and efficiency Downpipes and hot-side routing can reduce backpressure and improve turbo behavior. Pair with tuning and heat management for best results.
Weight and packaging Titanium, simpler routing, and race systems can reduce weight and free underbody space. Weight savings matter most when the system still fits and survives.
Sound quality Mufflers, resonators, crossover design, and tip style shape tone, drone, and aggressiveness. Street customers often care about tone almost as much as power.
Heat control and durability Coatings, shields, and smart routing protect nearby components and improve consistency. This is a major value point for turbo and track cars.
Upgrade Framing

Why Upgrade

A strong wiki should teach why a customer moves beyond stock in the first place. This is where the page connects product education to real driving results and purchase motivation.

Reduce restriction

Factory systems often balance cost, noise, packaging, and emissions first. Performance exhaust parts remove some of those compromises.

Shape the powerband

Headers, manifolds, and collector strategy can change where the engine pulls hardest and how sharp the car feels.

Lower thermal stress

A well-designed exhaust can help manage underhood and underbody temperatures, especially on turbo builds.

Improve sound with purpose

A proper system changes tone and presence without turning the car into a drone machine.

Support bigger mods

As airflow, boost, rpm, or displacement increase, the exhaust often becomes the next restriction.

Make service and fabrication easier

V-bands, smart routing, and modular sections can make maintenance and future upgrades much simpler.

Consequence Framing

What Happens If You Ignore It

Public education is stronger when it explains not only the upside of a part, but also the cost of doing nothing. This helps customers understand why support parts and system thinking matter.

Backpressure stays high

A restrictive system can hold back power, increase heat, and make turbo combinations work harder than necessary.

Heat damages other parts

Without proper shielding and routing, exhaust temperature cooks nearby wires, hoses, plastics, bodywork, and sensors.

Bad tone ruins the car

The wrong muffler or resonator plan can create harshness, rasp, or drone that makes the car less enjoyable to drive.

Cracks and leaks multiply

Weak mounts, thin tubing, poor welds, and no flex support cause leaks, rattles, broken studs, and fatigue failures.

Sensors become a mess

Poor bung placement and hacked routing make tuning, wideband use, and emissions maintenance harder later.

The customer buys twice

When sound is chosen before flow, fitment, and support hardware, many buyers end up replacing half the system later.

Merchandising

Performance Tiers

This section is important for sales because it helps the public self-sort into the right level of part without guessing.

OEM Replacement / Refresh

Restores stock-like function, fixes leaks or failures, and keeps the car reliable without chasing a big tone or power change.

Street Performance

Best for stronger tone, modest flow gains, daily drivability, and clean fitment.

Track / High Heat Use

Focused on heat control, clearance, durability, and consistent flow under repeated abuse.

Race / Extreme / Custom

Built for maximum flow, low mass, custom routing, and application-specific packaging.

Real-World Context

Real Build Examples

Example builds help the public understand where the part belongs, what should come with it, and how the performance result changes depending on the mission of the car.

Street Cat-Back Upgrade

Great for buyers who want a stronger tone, better flow, and easy installation without turning the car into a fabrication project.

Turbo Downpipe + Mid-Pipe Setup

Useful for turbo cars where faster response, lower backpressure, and a more aggressive sound are the main goals.

Header + Full Exhaust Naturally Aspirated Build

Shows how headers, crossover design, catalysts, resonators, and mufflers work together to shape both power and tone.

Track-Endurance Exhaust Package

Built around heat shields, strong hangers, serviceable joints, and resonators that keep the car legal and livable over sessions.

Minimal Drag Exhaust

Uses lightweight routing, simple exits, and collector strategy to reduce restriction and mass while keeping the system easy to inspect.

Fabricated Turbo Hot-Side and Specialty Exit

For custom builders packaging around swaps, turbo kits, or unique chassis constraints.

Important sales rule

Use examples to teach realistic combinations, not fantasy numbers. Public trust grows when the site shows what parts work together, what order to buy them in, and what results are realistic for each type of build.

Fast Navigation

Common Fix Paths

This is one of the best additions for usability. It gives readers a simple path from complaint to likely parts area before they read the full page.

Want more sound without terrible drone

Common path: Cat-back systems - Mufflers - Resonators - X/H/Y pipes - Tips

Tone shaping comes from the whole system, not just one muffler choice.

Turbo car feels choked or hot

Common path: Downpipes - Turbo outlet pipes - Wastegate routing - Heat shields - O2 support

Start by reducing turbine-exit restriction and controlling surrounding heat.

Headers keep leaking or cracking

Common path: Header gaskets - Studs - Locking hardware - Support brackets - Flex sections

Support and fastener strategy often matter as much as the header itself.

Custom system needs serviceable joints

Common path: V-bands - Flanges - Clamps - Flex sections - Hangers

Build modularity in from the start so the system can actually be removed and maintained.

Need emissions-friendly performance

Common path: High-flow catalytic converters - CARB legal parts - Smog legal mid-pipes - Sensor bungs

A smart legal setup often keeps the car far more usable than a minimal setup path.

Car rattles, scrapes, or melts nearby parts

Common path: Hangers - Isolators - Heat shields - Clearance routing - Tailpipe supports

Routing and support quality usually fix this faster than replacing the main pipes.

Why this section matters

Readers rarely want to start with a long article. They usually want to know where to look first. This section solves that immediately.

Audience

Who This Page Is For

Another strong layout upgrade that helps the page feel curated instead of generic.

Street Enthusiasts

Want stronger tone, moderate gains, and good fitment without ruining daily comfort.

Turbo Builders

Need downpipes, hot-side flow, wastegate routing, and thermal control that actually support the power goal.

Naturally Aspirated Performance Builds

Care about header design, scavenging, sound character, and keeping the powerband matched to the engine.

Track and Road Race Cars

Need high-clearance routing, strong mounts, repeatable heat control, and often sound-rule awareness.

Drag and Roll Race Cars

Usually prioritize low restriction, low weight, and easy service access over cabin refinement.

Fabricators and Custom Builders

Need tubing, merge parts, flanges, bungs, flex joints, and service hardware to build the system correctly.

System Basics

How This Category Fits The Build

Use this section to connect Technical Wiki parts to fitment, support hardware, service needs, and realistic performance goals.

Most buying mistakes happen when a part is treated as a standalone upgrade. The better path is to understand what the part changes, what nearby systems must support it, and what measurements or install notes need to be checked first.

For street cars, reliability, service access, and noise or comfort trade-offs matter. For race cars, repeatability, inspection access, rule compliance, spares, and setup consistency often matter just as much as peak performance.

Use the catalog groups below as a planning map: start with the main part family, add the support pieces, then confirm the installation requirements before checkout.

Fitment Path

Confirm vehicle, dimensions, mounting points, and compatibility before choosing the final part.

Support Path

Check the hardware, fluids, wiring, brackets, seals, tools, and service parts that make the install complete.

Use Case Path

Match the choice to street, track, drag, drift, off-road, show, tow, or custom fabrication priorities.

Common misunderstanding

A part can be high quality and still be the wrong choice when the build goal, supporting system, or installation constraints are ignored.

Performance Theory

Build Strategy

This section frames the real buying question: what result should Technical Wiki parts create, what trade-offs come with that result, and what needs to be planned before money is spent?

Backpressure vs power

Reducing restriction can free horsepower, but only if pipe size, collector design, and tuning stay matched to the engine.

Turbo heat is a system problem

Manifolds, downpipes, wastegate tubes, and shielding affect not just power but also engine-bay survivability.

Sound rules can shape the build

Road-race and endurance customers may need resonators, muffler selection, and tailpipe routing that meet venue limits.

Weight matters when it is positioned well

Light systems help, but durability and fitment still matter more than a few pounds saved in the wrong place.

Merge quality changes results

Collectors, X-pipes, and transition sections influence pulse behavior, tone, and overall efficiency.

Heat protection is a performance part

Keeping temperature away from intake charge paths, brake lines, fuel lines, and electronics helps the whole build stay consistent.

Best answer for performance

Choose the part that solves the build's actual constraint. Sometimes that means the highest-flow option; other times it means the most durable, serviceable, rules-compliant, or easiest-to-install option.

Core Hardware

Main Components

Technical tables feel much stronger when they are given a proper panel, spacing, and scanning structure.

Component Role Common Failures
Primary Assembly The main part family or assembly the shopper is researching. Wrong fitment, missing support hardware, poor service access, or mismatched build goals.
Support Hardware Fasteners, brackets, fittings, wiring, seals, fluids, or install parts that complete the job. Leaks, loosening, vibration, incomplete installs, or repeat labor from skipped small parts.
Control And Adjustment Settings, electronics, adjustment points, sensors, or calibration details that affect behavior. Unstable performance, warning lights, poor repeatability, or hard-to-diagnose behavior.
Service Items Consumables and replacement parts that keep the setup working after installation. Premature wear, noise, contamination, and reduced reliability.

Layout improvement here

The table now feels like a technical reference block instead of just dumped spreadsheet-style information. Better tables increase trust on a wiki page.

Deeper Detail

Component Deep Dive

Breaking larger component content into anchor sections makes the wiki more linkable and easier to scan.

Primary Assembly

Start by matching the main part to the vehicle, the build goal, and the installation space. A part can be well made and still be wrong if the mounting points, dimensions, operating range, or supporting system do not match the car.

Support Hardware

Small parts often decide whether the install feels professional. Check brackets, fittings, gaskets, fasteners, wiring, fluids, clamps, and service pieces before assuming the primary item is all that is needed.

Control And Adjustment

Many performance parts depend on setup. Adjustment range, electronics, alignment, calibration, preload, pressure, torque spec, or routing can change whether the final result is stable and repeatable.

Service Items

Plan maintenance before checkout. Consumables, replacement hardware, inspection access, and spare parts matter more as the vehicle moves from street use into track, race, tow, off-road, or custom fabrication work.

Complaint Patterns

Common Symptoms

Card variety makes symptom scanning faster and keeps the page from feeling flat.

Poor Fitment

Often points to wrong application data, missing brackets, incompatible trim, or dimensions that were not checked before ordering.

Noise Or Vibration

Can come from loose hardware, contact with nearby parts, worn service items, or an install that needs isolation or adjustment.

Inconsistent Performance

Usually needs a review of setup, calibration, supporting parts, wiring, routing, or maintenance condition.

Early Wear

Often caused by skipped support parts, contamination, heat, poor alignment, or incorrect torque and service procedure.

Troubleshooting Guide

Symptom to Cause Map

One of the strongest utility upgrades on a technical page is a direct complaint-to-subsystem map.

Symptom Likely Cause Area
Part does not fit Wrong application, trim difference, missing bracket, or unverified dimensions
Noise after install Loose hardware, contact point, worn support item, or insufficient clearance
Performance feels inconsistent Setup, calibration, routing, heat, or supporting system issue
Premature wear Incorrect install process, contamination, heat, alignment, or maintenance gap

Best use of this table

Use it to narrow your search direction before buying parts. It helps separate system-side issues from airflow or heater-side problems.

Workflow

Diagnostic Process

A step layout reads much better than a plain paragraph list for troubleshooting content.

1

Confirm the application

Verify year, make, model, trim, engine, drivetrain, dimensions, and any known platform split before buying.

2

Inspect the supporting system

Look for worn nearby parts, missing hardware, leaks, wiring issues, clearance problems, or previous modifications.

3

Check install requirements

Review tools, torque specs, setup ranges, calibration needs, fluids, brackets, and service parts.

4

Validate after installation

Test for clearance, noise, leaks, warning lights, movement, temperature, pressure, or other category-specific checks.

Buyer warning

Parts shopping before basic diagnosis is one of the most expensive mistakes on category system systems. Many symptoms overlap even when the failed part is completely different.

Preparation

Basic Tools

A small support section like this adds practical value and improves article flow.

  • Basic hand tools and sockets for exhaust fasteners
  • Penetrating oil and stud-removal tools for seized hardware
  • Inspection light and creeper for leak and clearance checks
  • Straightedge for flange checks
  • Infrared temperature awareness or thermal inspection tools
  • Welding and fabrication tools for custom routing work
  • Cutting and deburring tools for tubing changes
  • Wideband / AFR support for tuning-aware exhaust changes
Repair Categories

Common Repairs

Repair blocks should feel distinct from info sections so the user can scan solutions faster.

Leak Repair and Hardware Refresh

A common fix path for systems with broken studs, loose joints, failed clamps, or worn gaskets.

Muffler and Resonator Correction

Useful when the car sounds harsh, drones, or needs a more refined tone without rebuilding everything.

Downpipe or Mid-Pipe Upgrade

Often the most important change on turbo cars that still feel restricted or overly hot.

Header and Manifold Service

Critical when flanges warp, studs loosen, cracks form, or collector support is poor.

Catalyst Replacement

Needed when converters melt, clog, rattle, or no longer support the build or legal requirement.

Fabrication Joint Rework

A smart move when V-bands, clamps, flex sections, and transition pieces are causing repeat problems.

Heat Shielding and Protection Upgrade

Essential when nearby components are being cooked or floor and tunnel heat are out of control.

Sensor Bung and Data Port Update

Useful when wideband, O2, EGT, or backpressure support was poorly planned the first time.

Preventive Service

Maintenance

Maintenance sections read best when kept clean, direct, and easy to reference.

  • Inspect hangers, isolators, and clamps regularly because vibration slowly shifts even good systems.
  • Retorque accessible hardware after heat cycles on fresh installs.
  • Look for soot marks near joints because they reveal leaks early.
  • Check wrap, blankets, and shields for damage before nearby parts start cooking.
  • Inspect catalysts and mufflers for impact damage on lowered or off-road vehicles.
  • Review sensor wiring and bung condition whenever the system is apart.
  • Replace tired gaskets and hardware before they create recurring leak problems.
  • Treat unusual new rasp, rattle, or metallic noise as an early warning sign.

High-value maintenance item

The cabin air filter is one of the cheapest and highest-impact airflow maintenance items on the whole page.

Performance Focus

Performance Upgrades

This section is about real thermal gains, not random parts swapping or single-purpose thinking.

Direct Replacement

Best when the goal is restoring function, keeping installation simple, and avoiding unnecessary supporting changes.

Performance Upgrade

Best when the build has a clear performance limit and the surrounding system can support the higher demand.

Custom / Fabrication Path

Best when packaging, rules, power goals, or vehicle use require measuring, mockup, and supporting hardware.

Service Refresh

Best when reliability depends on replacing wear items, seals, hardware, fluids, or related maintenance parts.

Best upgrade mindset

The smartest category system upgrades improve heat rejection, airflow control, visibility, and driver function. They do not pretend the compressor is free or that deleting everything is always the fastest answer.

Shopping Strategy

Parts Buyer Guide

This section helps separate real thermal-planning purchases from guesswork and trend-driven deletes.

Choose for the real use case

Street tone, turbo flow, road-course heat control, and drag simplicity all prioritize different parts.

Do not buy only by sound clips

Recorded clips hide drone, harshness, and how the system behaves in the actual car.

Think about serviceability

Modular joints, good hardware, and smart routing save time and frustration later.

Plan for sensors and tuning

Widebands, O2s, catalysts, and data ports should be part of the plan, not an afterthought.

Respect emissions and inspection realities

The best street build is usually one the owner can live with legally and practically.

Support the main parts properly

Good gaskets, studs, clamps, hangers, and heat management protect the money spent on the larger parts.

Common buyer mistake

The biggest mistake is buying or deleting category system parts before deciding the actual mission of the car. A drag car, road-race car, street/track car, and rally car should not shop the same way.

Catalog Organization

Taxonomy Navigator

This section makes the catalog easier to browse by grouping the category depth into cleaner shopping lanes. It is the single-file version of taxonomy cleanup, so users can understand where to look before they ever hit the category page.

Attribute Guide

Strong auto-parts pages depend on consistent attributes. This guide shows the fields that should drive cleaner filtering, better comparisons, and clearer product context even inside a wiki article.

Flow Goal

Why it matters

Know whether the system is aimed at sound, peak power, turbo response, reduced restriction, or a balance of all of them.

Examples:

Sound Profile

Why it matters

Decide whether the customer wants deep, refined, aggressive, valved, track-focused, or nearly stock behavior.

Examples:

Heat Exposure

Why it matters

Turbo cars, tight tunnels, nearby wiring, and floor proximity all increase the need for thermal planning.

Examples:

Connection Style

Why it matters

V-bands, flanges, band clamps, and slip-fit joints all have different serviceability and sealing behavior.

Examples:

Emissions / Compliance Need

Why it matters

Street use may require catalysts, CARB-friendly parts, or retained emissions support.

Examples:

Use Case Durability

Why it matters

Track, drag, off-road, and custom fabrication builds need stronger supports and smarter routing than mild street cars.

Examples:

Best use of attributes

Keep the top-level category pages broad and clean, then use these attributes to guide internal filters, comparison tables, and support-part suggestions.

Avoid These

Common Mistakes

Useful for both technical readers and shoppers because it prevents the most common wrong turns.

  • Buying the loudest exhaust first without considering drone or tone quality.
  • Using too much pipe size for a mild combination and losing balance.
  • Ignoring heat management on turbo and track builds.
  • Forgetting bung placement until after coating or final welding.
  • Using weak clamps, poor hangers, or cheap gaskets next to expensive main components.
  • Deleting catalysts or resonators without thinking about smell, rasp, legality, or daily use.
  • Routing a custom exhaust without checking suspension travel and driveline movement.
  • Treating fabrication support parts like an afterthought instead of part of the main system.
Use Case Context

Vehicle Platform Notes

category system choices make more sense when they are tied to the exact motorsport or dual-purpose role of the vehicle.

Street Cars

Usually need the best mix of tone, fitment, emissions compatibility, and daily comfort.

Turbo Street and Roll Race Builds

Need downpipe flow, heat control, wastegate routing, and sound management that still works on the road.

Drag Cars

Often prefer low-restriction routing, minimal weight, and simple service access over cabin refinement.

Road Race and Drift Cars

Need clearance, durable mounts, repeatable heat control, and often track-friendly sound strategy.

Off-Road and Heavy-Duty Vehicles

Need strong hangers, impact-aware routing, flex support, and durable muffler and tailpipe choices.

Universal / Custom Builds

Need fabrication parts, modular joints, sensor support, and routing freedom above all else.

Trust Signals

Support & Buying Confidence

A racing parts site needs more than a parts list. It needs clear paths from research into fitment notes, buying guidance, return policy, and the right catalog section.

Match sound and performance honestly

We help separate loud from useful so buyers choose parts that fit the engine and the way the car is used.

Shop Exhaust Parts

Support the whole exhaust path

A strong system needs the right joints, sensors, hardware, and heat control, not just the biggest visible parts.

Shop Exhaust Parts

Build with future changes in mind

Modular joints, sensor support, and fabrication-ready parts make later turbo, engine, or tune changes easier.

Shop Exhaust Parts

Best buyer workflow

Decide whether the goal is intake cooling, cockpit control, visibility, or deletion first. Then match the hardware and support pages to that exact mission.

Quick Answers

Frequently Asked Questions

FAQ content works better when it is visually compact, searchable, and expandable instead of always open.

Showing all FAQ entries.

No FAQ entries match the current search. Try a broader category term, part function, fitment concern, install step, or maintenance topic.

For many street cars, a well-designed cat-back or axle-back brings the most noticeable change in tone and personality. The best answer depends on whether the real goal is sound, flow, or both.

No. Pipe size has to match the engine combination. Too much size can hurt velocity, response, and overall balance on mild setups.

They can be, especially when the stock manifolds are restrictive and the rest of the combo can use the improved flow. Gains depend heavily on the engine and supporting tune.

Because it directly affects how easily gases leave the turbine. That influences backpressure, heat, spool, and the turbo system's overall efficiency.

Drone usually comes from pipe size, muffler design, resonator strategy, crossover layout, engine firing behavior, and cabin resonance working together.

Often yes. Resonators are one of the best tools for reducing rasp and shaping unwanted frequencies even when mufflers are already present.

For many street builds they are. They can preserve much more daily usability and legality while still flowing far better than restrictive stock units.

Both can work, but V-bands are popular for modular, serviceable performance builds because they seal well and make disassembly easier.

Common causes include warped flanges, poor gasket choice, bad fasteners, missing support, and repeated heat cycling loosening the hardware.

It can help manage heat and protect surrounding parts. On some builds that supports consistency and component survival more than a raw dyno number.

Before You Buy Checklist

This checklist is one of the best tools for reducing returns and increasing confidence. It slows down bad purchases and speeds up the right ones.

  • Decide whether the goal is sound, power, turbo flow, heat control, weight reduction, or all of them together.
  • Confirm emissions and inspection needs before buying delete parts or specialty routing.
  • Choose tubing size and muffler strategy for the actual engine, power level, and use case.
  • Plan sensor bung locations and wideband access before final welding or coating.
  • Review hanger support, flex sections, and service joints so the system survives vibration and heat cycling.
  • Leave room for nearby suspension travel, driveline movement, and ground clearance.
  • Treat coatings, blankets, and shields as part of the build when temperatures are serious.
  • Budget for the support hardware, gaskets, and fasteners instead of only the main shiny parts.

Why the public responds well to this

Buyers do not mind being told to slow down when the checklist obviously protects their money, their install time, and their build plan.

Take Action

Next Step for Research or Shopping

This close should help the reader choose the right thermal path, not just dump them at the bottom of the page.

Use this page to decide whether the car needs more support core control, a retained support and safety path, better driver-area airflow, a lightweight compact category system answer, or a minimal setup. If intake-air cooling with AC is on the table, treat it like a full engineering project and compare the thermal gain against the drag and packaging cost.
