Developed for the Mini Cooper S, this Billy Boat Performance Exhaust cat back exhaust is precision crafted using 100% T304 stainless steel. Through a combination of sound cancelation and absorption the straight through design muffler offers a deep rich exhaust note on acceleration with a mild tone at idle and cruising speeds. This along with CNC mandrel bent tubing allows for a smooth uninterrupted exhaust flow for increased horsepower and torque. Installation is simplified with this completely bolt-on system. Absolutely no cutting, welding or modifications are needed for installation! Twin 3” round rolled edge tips gives the car an individual look. With no engine management sensors moved or altered this system is 50 state emissions legal and is backed with their limited LIFETIME warranty.
