Description

A 5" from the down-pipe 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 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
  • Bayonet OE Style / Welded-On Hangers

Most Popular Questions

By looking at the pic, is the front pipe diameter immedietly 5" after the flange? Or does it go from 4" to 5"? I've looked at the MBRP 5" downpipe back system and it looks like it doesn't expand to 5" until sometime after the connection flange. The pic of the AFE system shows no expansion, so is it 5" right away with no 4" to 5" increase?

Answer

An upgraded performance exhaust system can be installed on a completely stock truck. Performance exhaust systems increase exhaust flow by eliminating the restrictive stock muffler, replacing factory crimped bends with smooth mandrel bent tubing, and increasing the overall pipe diameter. The benefits of increased exhaust-flow are reduced EGT's (exhaust gas temperature), increased horsepower/torque, increased fuel mileage, and a that deep throaty diesel sound.

could i mount this exhaust up as a side pipe that exits in front of the right rear tire?

Answer
The AFE ATLAS 5" Aluminized Exhaust System w/o Muffler (Downpipe-Back) 49-04007NM is designed for a traditional "out-the-rear" exit. Any other configuration would have to be custom fabricated and installed by the end user.
