The AFE 49-02047NM-1 ATLAS 5" Turbo-Back No Muffler Race Exhaust System for your 2013-2017 Dodge Ram 6.7 Cummins features a true 5" design from the turbo-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 reduced EGTs. This "straight-pipe" kit comes without a muffler or exhaust tip (sold separately). 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 in place of the muffler for a true race-inspired sound and maximum flow.

OE 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 reduced EGTs.

Great product with a few kinks

Order #454070 I had two issues with this exhaust. The first is the band clamps supplied with the kit did not work very well. Snapped a couple of the bolts trying to get them tight enough. I opted to replace them with some heavy duty u-bolt style clamps from the local parts store. The big issue was that I could not get the down pipe to fit with the transmission crossmember in place. If there is a trick to it I couldnt figure it out. I ended up cutting about 14" off the pipe and it went right in. The kit comes with an extra pipe to accomodate for SB/LB so I cut the extra piece which was alread flanged to replace the down pipe section I removed and it worked great. Seems like this could be a design improvement. Issues aside the pipe works excellent and everything else fit very well. installation was a snap. I would buy this again becuase the pipe cutting was not an issue for me but would be rather upset if that was not the case or if the extra piece was not available to replace it.
