aFe 49-44002 4″ 409 Stainless Steel Cat-Back Exhaust System

Flow and Performance:
The aFe 49-44002 4? 409 Stainless Steel Cat-Back Exhaust System is constructed from 4? mandrel-bent 409 stainless-steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower and torque and lowering EGTs.

Installation Is a Snap:
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 free-flowing 24? long muffler absorbs high-pitched tones, producing a powerful sound and unleashing all available horsepower and torque out of your rig. A muffler delete pipe is also included for those who prefer a true race-inspired sound and maximum flow.

Perfect Fit:
OE-style bayonet hangers 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.
