Precision crafted using 100% T-304 stainless steel and mandrel bending, this 335i TT Sport exhaust system with black tips is the more aggressive of the two offered by B&B and not for the weak at heart. By utilizing the factory mounting locations for an easy installation this system requires a single cut of the factory system on each side to remove and comes with all the necessary mounting hardware.

Incorporating the latest in resonance control technology, B&B’s proprietary Purge Resonance Technology or PRT as it is known, allows you to have a mild exhaust note at cruising speeds yet a forceful note on aggressive driving. This low restriction muffler allows for less turbo lag, faster spool up for quick acceleration and increased horsepower and torque. These results have been confirmed by the chassis dyno and by our customers. To give the car a bold and demanding look B&B uses a pair of 4” round double wall black tips.

No engine management sensors are moved or altered therefore this system is 50 state emissions legal and is backed with their limited LIFETIME warranty.

Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
