Billy Boat Performance

Since 1989, Billy Boat Performance Exhaust systems have incorporated 3-generations of fabrication skill and racing talent inherited from the Boat Family. B&B starts with T-304 stainless steel known throughout the industry as the highest quality material practical for automotive exhaust applications. All exhaust tubing is mandrel bent on sophisticated CNC machinery for precise fit and uninterrupted exhaust flow. What's more, the use of T-304 stainless steel flanges offers precision fit and complete resistance to harsh elements. All hangers, resonators and tips are T-304 stainless steel as well. Every muffler is built in-house with years of racing and street development invested into its design. Each muffler is tuned to match its application for the best possible performance gain and sound quality combination. Stress relieved end plates, gussets and TIG welding ensures awesome strength and rugged durability.

Exhaust

Burning fuel in the engine of your BMW or MINI produces a lot of sound along with nitrogen oxide, carbon monoxide, hydrocarbons and other harmful gases during the combustion process. Your vehicle's exhaust and emissions system helps control some of that sound and cleans up the gasses in the process of routing them out of the engine bay.

For more than four decades, Bavarian Autosport has been helping BMW and MINI enthusiasts maintain, repair, and upgrade their vehicles while saving thousands of dollars in shop fees.

And if you aren't 100% satisfied with your purchase, returns are easy and hassle-free.
