Product Details

Since 1989, Billy Boat has been designing, testing and producing quality exhaust systems for your vehicle. These systems improve air flow, giving you more power, while at the same time giving you an incredibly racy sound.

Billy Boat's A4 Exhaust is a complete stainless steel 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 BB exhaust includes a 2.5" downpipe.

The exhaust then continues back to the innovative center muffler where it splits into dual 2.25" pipes. Each of these mandrel bent pipes goes to its own muffler with a 3.5" rolled round tip. 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.

All BB exhausts come with a full lifetime warranty.

Now that you have a new exhaust system, why not improve your air flow elsewhere? Cold Air Intakes are a great way to add some extra power to your vehicle. Check under the Engine section for all your performance part needs.
