Since 1989 Billy Boat Performance Exhaust has designed, tested, and manufactured the highest quality stainless steel exhaust systems available. Originally specializing in Porsche 911 performance exhaust systems, oil coolers, and intercoolers, B&B introduced the Tri-Flo line named after its unique 3-into-1 Porsche header. Today in its state-of-the-art facility, Billy Boat continues to develop the highest performing exhaust systems for most sports cars, trucks, and SUVs. With an in-house dyno facility and R&D staff, we stay on top of current vehicle trends and deliver products that fit and perform to an unsurpassed level of standards. .....Each Billy Boat Performance Exhaust system incorporates 3-generations of fabrication skill and racing talent. Every system starts with T-304 stainless steel, known throughout the industry as the highest quality material practical for "after-cat" exhaust applications. All exhaust tubing is mandrel bent on sophisticated CNC machinery for a precise fit and uninterrupted exhaust flow. What's more, the use of T-304 stainless steel flanges offers high strength and complete resistance to harsh elements. All hangers, resonators, and tips are T-304 stainless steel as well.

.....Billy Boat Performance Exhaust mufflers are crafted in-house with years of racing and street development invested into the design. Each muffler is tuned to match its application for the best possible performance gain and sound quality combination.

.....For strength, the muffler end-plates are radiused at the inlet and outlet preventing premature cracking. Additionally, reinforcing gussets are used when necessary. Depending on the application, you can choose from 3" round tips with a rolled edge, 4.5" oval rolled edge tips, 5.25" oval rolled edge tips or DTM style tips for European applications.
