Billy Boat's catback system is a complete stainless steel mandrel bent cat-back exhaust. The exhaust is a dual 2.5" system that begins at the factory catalytic converter and continues to 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 ture-dual system finishes nicely with fully polished twin 3" double wall tips.
