CORSA builds this cat-back from 3.0 inch 304 stainless steel and routes it to a front axle exit, bringing the outlet out ahead of the rear tire rather than past the bumper. What separates it from a plain muffler swap is the tuning: CORSA's Reflective Sound Cancellation cancels the specific frequencies that cause cabin drone, so the truck gets an aggressive note under throttle and stays quiet at highway cruise. The system flows better than stock and weighs less, finishes in twin 4.0 inch dual-wall polished stainless Pro-Series tips, and bolts on with no welding or cutting. Printed instructions are in the box and CORSA backs it with a limited lifetime warranty.
