The new ATLAS exhaust race pipe is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4" aluminized steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's.

To provide a leak-free seal, OE style flanges are used that offer a 36 sealing area. ATLAS exhaust race pipes are the perfect combination of performance, fit and value.
