For the true enthusiast Billy Boat Performance Exhaust developed these cat delete pipes to upgrade the B&B cat back along with the OE manifolds. Manufactured from 3” CNC mandrel bent T304 stainless steel these pipes eliminate the restrictive OE cats for better exhaust flow and more horsepower and torque. With great attention to detail these pipes were designed to be a direct bolt on part, include all necessary hardware and are backed by B&B’s limited LIFETIME warranty. *THESE UNITS ARE DESIGNED FOR OFF-HIGHWAY RACING ONLY AND SHOULD NOT BE USED ON PUBLIC ROADS*
