Stainless Steel Cat-Back Exhaust System

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 Boats's A6/Allroad 2.7T Exhaust is a stainless steel mandrel bent cat-back exhaust. Our exhaust begins after the factory catalytic converters with dual 2.5" pipes and continues back to the innovative center muffler. From there it splits to two separate mufflers placed in the factory location.

This exhaust really helps to awaken the 2.7T but keeps the stateliness that it deserves. With TIG welding fully stainless construction and CNC'd hangers you will not find a higher quality system on the market.The 2000 and 2001 A6 2.7T exhaust has a pair of stealthy downturns just like the factory. The 2002 A6 and Allroad 2.7T exhaust has twin 3.5" Tips utilizing the factory valence openings.

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.
