Corsa's Sport cat-back is a 3.0 in dual rear exit system in 304 stainless steel that flows better than the stock exhaust while its patented Reflective Sound Cancellation technology tunes out cabin drone. The result is an aggressive note under acceleration and a quiet, drone free cruise, with the sound choice kept separate from the performance gains. Bolt on installation reuses the factory tip bezels, needs no welding, and is backed by a Limited Lifetime warranty. Made in the USA.
