Elevate the performance and driving excitement of your vehicle with the Corsa Sport Cat-Back Exhaust System (Polished). Featuring Corsa's signature Sport sound profile, this system delivers a +12 dB increase over stock under acceleration, offering a bold and refined growl that matches your HEMI’s muscle, while maintaining drone-free comfort inside the cabin. Constructed from 304L stainless steel, this 2.5" cat-back system uses a non-restrictive, straight-through design to reduce back pressure, improve exhaust flow, and boost both horsepower and torque. The system also delivers a weight savings of 13 lbs over stock, contributing to improved overall vehicle dynamics. The system exits through dual rear polished 4.5" Pro-Series tips with a dual wall slash cut, giving your Grand Cherokee a clean, aggressive look. Installation is straightforward—no welding required—thanks to TORCA stainless clamps and included hardware with detailed, full-color instructions.
