The Large Bore-HD exhaust race pipe is engineered to perform in the most extreme environments. This system is constructed from 4" mandrel bent stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. Large Bore-HD exhaust race pipes 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.
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 race pipes are constructed of 4" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
