The ATLAS exhaust race pipe is engineered to perform in the most extreme environments. This system is constructed from 4" mandrel-bent aluminized tubing for maximum flow, increased horsepower, increased torque and lower EGT's. The ATLAS exhaust race pipe is the perfect combination of performance, fit and value. Leak-Free Seal: High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface. Perfect Fit: 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: The ATLAS race pipe is constructed of 4" mandrel-bent aluminized tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
