CORSA routes this 3.0 inch cat-back to a Lightning exit, bringing the outlet forward of the rear tire, and builds the whole system from 304 stainless steel. The mufflers use CORSA's Reflective Sound Cancellation to cancel the frequencies that cause cabin drone, so the truck gains an aggressive note under throttle without the highway boom that usually comes with it. Flow improves roughly 15 percent over stock and the system sheds about 35 pounds against the factory exhaust. It finishes in twin 3.5 inch dual-wall black PVD Pro-Series tips, bolts on with no welding or cutting, and carries CORSA's limited lifetime warranty.
