The new Large Bore HD exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel-bent 4" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT. This system is available in 4" cat-back with muffler. 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.
