The Corsa Extreme Cat-Back Exhaust System is the ultimate performance upgrade for your vehicle. Designed to match the power and presence of your HEMI engine, this system produces a deep growl at idle, bold tone on acceleration, and an all-out roar at high RPMs—all without interior drone, thanks to Corsa’s patented Reflective Sound Cancellation® (RSC®) technology.

Crafted from premium 304 stainless steel, the 2.75" straight-through system delivers a +81.41% increase in exhaust flow, resulting in an average gain of up to 10 horsepower and 13 lb-ft of torque, while shedding 7 lbs. compared to stock. You can choose between twin 3.5" polished or black Pro-Series dual-wall tips, adding an aggressive finish to your rear profile.

This bolt-on system requires no welding, and every kit includes all necessary hardware and a detailed instruction manual. Whether cruising the streets or tearing up the vehicle, the Corsa Xtreme system transforms your Challenger’s performance and sound.
