The Crossmember Back Exhaust System is ideal for enthusiasts seeking an aggressive to moderate interior and exterior sound level. However, thanks to an H-pipe style crossover, you won't have to put up with overwhelming drone. The built-in H-pipe crossover is also great for improved exhaust gas scavenging. The system consists of all mandrel-bent 2.50-inch stainless steel tubing and includes all hardware necessary for installation.
