Frequently Asked Questions
What's the difference between a performance exhaust and a replacement exhaust?
Performance exhaust systems are designed for improved flow, power gains, and better sound - they use larger diameter pipes and free-flowing mufflers. Replacement exhaust systems match OE specifications for quiet, stock-like operation. Choose performance for upgrades or replacement if you just need to fix a rusted or damaged exhaust.
How much horsepower does an exhaust system add?
Performance exhaust systems typically add 10-20 horsepower on naturally aspirated engines and 20-40+ horsepower on forced induction engines. The exact gains depend on your engine, existing restrictions, and how much of the system you upgrade. Full systems (headers to tailpipe) offer the most gains; cat-back systems are the most popular balance.
Should I get a cat-back or axle-back exhaust system?
Choose cat-back for maximum performance and sound improvement - it replaces more of the exhaust for better flow. Choose axle-back for a budget-friendly sound upgrade with easy installation. Axle-back gives you new mufflers and tips for less money, while cat-back delivers a more complete transformation of sound and performance.
Will an aftermarket exhaust system void my vehicle warranty?
A cat-back or axle-back system typically won't void your warranty because they don't affect emissions equipment. Under the Magnuson-Moss Warranty Act, dealers must prove the aftermarket part caused a failure. However, modifying emissions components (removing cats) can void related warranty coverage. When in doubt, ask your dealer.
Is stainless steel or aluminized exhaust better?
Stainless steel costs more but lasts longer - often 10+ years or the life of the vehicle. It resists corrosion and looks better over time. Aluminized steel is more affordable and adequate for 5-8 years in moderate climates. Choose stainless if you keep vehicles long-term or live in areas with road salt and harsh weather.
