Description

The AFE 49-44060 Large Bore HD 5" Downpipe-Back Exhaust System for your 2001-2004 GM 6.6L Duramax is engineered to perform in the most extreme environments. This system is constructed from 5" mandrel bent stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGTs. This system uses high quality band clamps, OE-style bayonet hangers and includes an adjustable hanger clamp for a tight secure fitment. This system is available with a free-flowing 24" long muffler and includes choice of polished stainless steel or powder coated black 6" diameter clamp-on tip with a laser-cut stainless steel aFe power plate for an aggressive style.

Installation is a Snap:

Leak-Free Seal:
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.
