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.
Axle-Back Exhaust
An axle-back only replaces the mufflers and tips at the very rear of the car — the simplest and cheapest exhaust upgrade. It mainly changes the sound character with minimal power gains. Perfect as a first mod if you want a better exhaust note without a big investment.
