The new ATLAS exhaust was engineered to perform in the most extreme environments. These systems are constructed from mandrel bent aluminized steel tubing to increase exhaust velocity to maximize horsepower and torque gains, while lowering EGTs. The 2-piece tailpipe and bayonet style hangers provide a hassle-free installation. To provide a leak-free seal, OE style band clamps are included to offer an improved seal.
