A 5" from the down-pipe back, the ATLAS exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 5" aluminized steel tubing for maximum flow, increased horsepower, increased torque and lower EGT’s. This system is available in 5" down-pipe back without 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 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.

I found the hardest part from start to finish was the connect to the down pipe just have a friend makes it Easy this way I did find one down side the pipes fit prefect or to the dot that u can get them to connect and had to use a pillars and carefully bent the connects out to fit over the starting pipes all the way back with a pre set champ However this system is nasty it turns heads if u wanna be heard type deals.
