Description

The AFE 49-42054 Large Bore HD 4" Turbo-Back Race Exhaust System for your 2013-2017 Dodge 6.7L Cummins is engineered to perform in the most extreme environments. Featuring 4" mandrel bent stainless steel tubing for maximum flow, increased horsepower, increased torque and reduced EGT's. This system is available with a free-flowing 24" long muffler and a 6" diameter polished stainless steel clamp-on tip with a black laser-cut stainless steel aFe power plate for an aggressive style. 

Installation is a Snap:
This Large Bore HD exhaust system includes an extension pipe to fit cab configuration and uses factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:
A high quality OE style flange and band clamps are used for a complete 360 degree sealing surface.

Aggressive Sound:
A free-flowing 24" long muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.

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:
This Large Bore HD exhaust system is constructed of 4" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

Exhaust Tip:
Finishing off the exhaust is your choice of a high luster or black powdercoated 6" diameter stainless steel clamp-on tip with a laser-cut stainless steel aFe power plate for an aggressive style.

Im looking at putting this on a stock 2016 cummins i know i need a programmer but does the truck need to be deleted?
View Staff Answer 
Answer
This exhaust will remove the DPF and DEF system from the truck which is considered "deleting". If you do not wish to delete your truck, look into "Filter-back" exhausts. No tuner is required for these types of exhaust since they bolt to your existing factory emissions equipment.
