The CORSA Xtreme Cat-Back Exhaust System for the vehicle delivers the sound and performance that turns a luxury cruiser into a bold street presence. Engineered for muscle car enthusiasts who want an aggressive tone without interior discomfort, this system blends raw sound with refined engineering. CORSA’s Xtreme sound profile is the most aggressive in their lineup—perfect for those who want their HEMI to growl at throttle and rumble at idle. Inside the cabin? It stays calm and drone-free thanks to Reflective Sound Cancellation® (RSC®) Technology, which eliminates harsh frequencies at cruising speeds. Crafted from 304L stainless steel and built with a 2.5” straight-through mandrel-bent design, this system delivers a 61% increase in exhaust flow over stock. The result is an average gain of up to 10 horsepower and 13 lb-ft of torque, plus a 10-pound weight reduction. Featuring dual rear exits with single 4.5” Pro-Series dual-wall slash-cut tips, this system is a performance upgrade that looks as good as it sounds. With no welding required, installation is straightforward and emissions-compliant in all 50 states.
