Billy Boat Performance Exhaust developed this cat back for the 6.2L Cadillac Escalade with years of racing and street development into its design. Manufactured form only the highest quality T304 stainless steel materials, this true dual system has a single 3.5” tube leading into the muffler with two 2.5” pipes exiting the muffler and is a direct bolt on replacement for the restrictive factory exhaust. CNC mandrel bent tubing for a smooth, uninterrupted exhaust flow and a straight through design muffler incorporating B&B’s proprietary Purge Resonance Technology (PRT) the system emits a deep, muscular note on hard acceleration yet a mild tone at cruising speeds without the unwanted interior resonance thanks to the unique purge chamber. Improved throttle response and increases in both horsepower and torque can be expected with this system. A pair of bold, yet stylish 4” round double wall tips exiting in the factory location will be sure to give the Escalade a distinctive look. With unparalleled quality and attention to detail this 50 state emissions legal system is backed with B&B's limited LIFETIME warranty.
