Description

The AFE 49-04054NM ATLAS 5" Down-Pipe Back No Muffler Race Exhaust System for your 2015.5-2016 GM 6.6L Duramax is built and engineered to performance in the most extreme environments. This off-road race exhaust system is constructed from mandrel bent 5" aluminized steel tubing for maximum flow, increased horsepower, increased torque and lower EGTs. 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 EGTs.

  • 5" Aluminized Steel Construction
