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 flange and band clamps are used for a complete 360 degree sealing surface.
Aggressive Sound: A muffler delete-pipe is used for a true race-inspired sound and maximum flow.
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 5" mandrel bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
