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.
