Billy Boat Cat-Back Exhaust for 2004-07 Audi RS6 [C5] - FPIM-0580

Billy Boat Performance Exhaust is the first manufacturer to offer a 100% T-304 stainless steel exhaust system for the Audi RS6. This high-performance system begins at the factory catalytic converter with 2.5"" tubing and exits the center muffler with dual 3"" tubing. The 3"" tubing continues to fully-polished low-restriction mufflers that hang in the factory mounting location. This true-dual system finishes nicely with fully polished twin 3"" double-wall tips.

Installation is simplified with this completely bolt-on system. Absolutely no cutting, welding or modifications are needed for installation! This true-dual system is TIG welded and completely mandrel bent resulting in a precision fit and an even exhaust flow.
