Product Details


This 3 inch twin-tipped cat back is at your service.  Extensive research and development time was spent designing a system which delivers in both sound quality and performance.  Built from scratch, this is a complete high performance exhaust system for the Audi A3.  The aftermarket product comes with a deep, full-bodied note. Yet they have completely reengineered it to include a sublime, mellow touring overtone. Billy Boat's unique purge chamber allows for our highest-standard true straight-through exhaust passage--even under aggressive driving conditions--that all Billy Boat exhaust systems must meet before they send them to market.  Extensive dyno testing on our in-house dynamometer afforded us impressive horsepower and torque gains throughout the entire power band. The entire system is meticulously built by hand using T304 Stainless Steel for a lifetime of performance, guaranteed!
