The new ATLAS exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4-inch aluminized steel tubing for maximum flow, increased horsepower, increased torque and lower 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 used that offer a 360degree sealing area. Systems are available in 4-inch turbo back some offer the choice of a 4-inch down-pipe back with or without muffler. ATLAS exhaust systems are the perfect combination of performance, fit and value.
