Exhaust
Your exhaust system carries spent gases away from the engine. A freer-flowing exhaust lets the engine push gases out faster, which means it can pull fresh air in faster too — more air in means more power out. Beyond performance, the exhaust is the #1 way to change how your Challenger sounds. From a subtle rumble to a full-on race car scream, the exhaust defines your car's voice.
Cat-Back Exhaust
A cat-back exhaust replaces everything from the catalytic converters back to the tips. It's the most popular exhaust mod because it's legal everywhere (the cats stay in place), changes the sound significantly, and adds some power. Different brands have very different sound profiles — from refined to aggressive.
