Billy Boat's Performance mufflers are a stainless steel mandrel bent design, featuring TIG welding, fully stainless construction and CNC'd hangers. You will not find a higher quality system on the market. Includes dual 4" double walled exhaust tips for a aggressive look.

Billy Boat mufflers begin after the factory X pipe and fit directly to the stock X pipe with the included adapters. This is a true performance exhaust, removing the stock change over valve allowing the most sound available.
