Customer Testimonial

Thanks Modbargains for all the help on my decision on the B&B axle back exhaust! I love the sport, it sounds amazing and absolutely no drone.  You guys are very helpful, ill definitely be coming back for some Avant Garde wheels!

- Brian K.

Aesthetics were another important factor in the development and design of this muffler system. Simply providing performance gains and a balanced exhaust note were not enough to declare this the ultimate system for the expertly engineered BMW E90/E92. With a fully-polished muffler and twin 3.5" fully-polished double-wall tips the Billy Boat system delivers well beyond expectations. 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.

Billy Boat Touring Mufflers for BMW 335i E90/E92/E93 - FBMW-1025

Touring Mufflers

What is the difference between the Sport and Touring Exhaust Systems?

Touring Exhaust: The Touring Exhaust has a bi-modal design like the original factory system, with a vacuum activated butterfly valve on the driver side muffler, which helps to give no cabin drone and a milder exhaust note. This is a great system for everyday drivers looking for a factor replacement with better performance and a nice exhaust tone.

Sport Exhaust: The Sport Exhaust has a smaller round muffler without the vacuum activated butterfly valve and is a much more aggressive system. This system does not guarantee that there will be absolutely no cabin drone however it does provide higher horsepower and torque gains, as well as a louder and more aggressive exhaust tone. This exhaust is perfect for each an everyday driver or for a weekend race car. It is the best exhaust on the market that gives you the best of both words.
