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.
