Upgrade your M3's exhaust with the newly released Billy Boat Performance Exhaust. The B&B Performance Exhaust features full T304 stainless steel construction and incorporates B&B's Purge Resonance Technology. B&B's Purge Resonance Technology (PRT) allows the exhaust to emit a deep exhaust note, without the unwanted cabin drone or resonance. The entire system is fully polished to provide a finish unlike that of any other exhaust on the market. All mounting hardware necessary is included, and no welding is required, and as always with B&B exhaust systems a limited lifetime warranty is included.
Give your E90 or E92 M3 a deep rumble, while increasing performance by 12 horsepower and 11 Ft./Lbs of torque at the rear wheels.
