Description

The AFE 49-04021 ATLAS 4" Race Front Pipe for your 2011-2015 GM 6.6L Duramax is built to perform in the most extreme environments. This system is constructed from precision, mandrel bent 4" aluminized steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. To provide a leak-free seal, OE style band clamps and flanges are used that offer a 360 sealing area vs. cheap U-bolt clamps used in other systems. ATLAS exhaust pipes are the perfect combination of performance, fit and value.

Installation is a Snap:
All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:
High quality OE style band clamps and flanges are used for a complete 360 sealing surface. Standard U-bolt clamps used by other systems only seal at the bottom and top of the tube allowing leak paths.

Flow and Performance:
ATLAS exhaust pipes are constructed of precision, mandrel bent 4" aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

Features:

  • 4" Mandrel Bent Aluminized Steel
  • For Race Use Only

Fitment Note: This front pipe 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.

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