Description

The AFE 49-04035NM ATLAS 5" Down-Pipe Back Race Exhaust System for your 2011-2015 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 eliminator-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.

Features:
  • 5" Aluminized Steel Construction
  • Down-Pipe Back Race Exhaust
  • No Muffler
  • No Tip 

Warning: This free-flow race exhaust system requires the use of an aftermarket performance programmer with off-road tuning.


Fitment Note: This exhaust will only fit 2015 models manufactured before July 2014. Models built after July of 2014 are equipped with a 3-bolt down pipe flange connection that is not compatible with this product.
