The Dinan High Flow X-Pipe produces a deeper note and a greatly aggressive sound that is coupled with a significant improvement in volume. With the combination of the Dinan exhaust and this Dinan high flow x-pipe, the perfectly aggressive growl is achieved. The Dinan High Flow X-Pipe is carefully engineered to provide optimum flow characteristics, and their design is simply a work of art. This product eliminates the factory middle section, as well as the secondary catalytic converter and the large resonator. Once removed, what you can see is a straight-through, mandrel bent, premium T304 stainless steel tubing and the custom-built "X" for enhanced flow process. With this improvement and modification, the exhaust system produces a dramatically enhanced aggressive throaty tone that can turn heads in admiration.
