Large Bore HD exhaust systems are the perfect combination of performance, fit and value.
Installation is a Snap:
All systems use factory mounting locations providing stability and hassle-free installation.
High quality OE style flange and band clamps are used for a complete 360-degree sealing surface.
A free-flowing 24" long muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.
OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.
Flow and Performance:
Large Bore HD exhaust systems are constructed of 4" mandrel bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT.
