    The new ATLAS exhaust 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 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 360º sealing area. A 12" free-flowing straight-through designed muffler is used to produce a deep, powerful sound. Systems are available in 4 down-pipe back with muffler. ATLAS exhaust systems are the perfect combination of performance, fit and value. Installation is a Snap: ATLAS exhaust systems utilize a 2-piece tailpipe design for a perfect fit by allowing adjustability at the tailpipe section. All systems use factory mounting locations providing stability and hassle-free installation. Leak-Free Seal: High quality OE style band clamps are used for a complete 360º sealing surface. Aggressive Sound: A free-flowing 12" wide muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig. 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: ATLAS exhaust systems are constructed of mandrel bent 4" aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs. Note: This is a "Race Only" product used solely for competition. It's use is limited to closed-course and open-course racing that is formally sanctioned by a recognized racing organization. Any other use including recreational off-road use, could be in violation of local, state and federal laws.
