B5 A4 1.8T Quattro / Twin 3" rolled edge polished tips

Billy Boats's A4 Exhaust is a stainless steel 2.5" mandrel bent cat-back exhaust. On an A4 the catalytic converter is bolted to the turbocharger and then the exhaust begins with the downpipe. Unlike most other aftermarket exhausts the Billy Boat exhaust includes a downpipe. This exhaust is very quiet and simply changes the tone of the exhaust to a deep unobtrusive sound. With TIG welding fully stainless construction and CNC'd hangers you will not find a higher quality system on the market.
