CORSA's patented Reflective Sound Cancellation (RSC) Technology lets their acoustic engineers cancel drone at its source, so this 3.0 in cat-back gives an aggressive note under acceleration and a drone free cabin at cruise, and the performance gains do not change with the sound choice. The system is built from 304 stainless steel, flows better than stock and weighs less than stock, and it bolts on with no welding required. It routes out ahead of the rear axle and finishes in twin 4.0 in dual wall stainless steel tips with a black finish. Detailed printed instructions are in the box, with full color instructions available online. Made in the U.S.A. and covered by CORSA's limited lifetime warranty.
