This cat-back gives your 09+ Corvette the rich, aggressive rumble that has made the Loudmouth one of our best-selling systems. The secret to its unique sound are the polished, SLP-stamped stainless "shotgun-style" resonators. It will turn heads on the street, at shows, and at the track with its incredibly powerful sound. If you're looking for something with a little more refined note, check out the Loudmouth II™, now also available for your 09+ LS3.
