The AFE 49-02054NM ATLAS 4" Turbo-Back No Muffler Race Exhaust System for your 2013-2018 Dodge Ram 6.7L Cummins features a 4" mandrel-bent aluminized construction for maximum flow, horsepower, increased torque, and lower EGT's. This "straight-pipe" turbo-back race exhaust system includes a muffler delete-pipe for true race-inspired sound and maximum flow. ATLAS exhaust systems are the perfect combination of performance, fit and value. Exhaust tip not included. Limited 2-year warranty.

Installation is a Snap:
This ATLAS exhaust system includes an extension pipe to fit multiple cab configuration and uses 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 4" mandrel bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and reduced EGTs.
