Developed for the BMW E60 530, this Billy Boat Performance Exhaust axle 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. While a simple cut is required to remove the stock muffler the B&B system mounts in the factory hangers for an easy do it yourself installation. Twin 3.5” round double wall tips gives the car a bold, distinctive look. No engine management sensors are moved or altered with this system therefore it is 50 state emissions legal and is backed with their limited LIFETIME warranty.
