Exhaust

Cat-back exhaust replaces everything from the catalytic converter back, improving flow and sound. Axle-back replaces only the muffler and tips for a more affordable sound upgrade. Cat-back systems offer greater performance gains.

Yes, performance exhaust systems reduce back pressure, allowing the engine to expel exhaust gases more efficiently. Expect 5-15 horsepower gains depending on the system and engine. Pairing with a tune maximizes the benefit.

Consider sound level, performance goals, and budget. Chambered mufflers offer a deep tone, glasspacks provide an aggressive sound, and turbo-style mufflers offer moderate sound with good flow. Stainless steel mufflers resist corrosion better than aluminized steel.

Exhaust wrap insulates headers and exhaust pipes to reduce under-hood temperatures and improve exhaust scavenging. Use it for performance applications where heat management is critical. Titanium wrap is more durable than standard fiberglass wrap.

Identify the leak location by feeling for escaping air or listening for changes in engine sound. Small leaks at joints can be repaired with exhaust sealant, while larger holes may require patching or section replacement. Rusted sections should be cut out and replaced.
