Overview

The aFe 49-42005 Mach Force XP 4" Cat-Back Exhaust System is designed for 2003-2004 Dodge 5.9L Diesel 2500 and 3500 trucks with the 235HP engine and catalytic converter.

This cat-back system is constructed from mandrel-bent 4-inch, 409 stainless steel tubing to improve exhaust flow and help reduce Exhaust Gas Temperatures (EGTs). It features a 24-inch free-flow muffler designed to absorb high-pitch tones for an aggressive exhaust sound. The system utilizes OE-style bayonet hangers and band clamps for stability and a secure seal, and it mounts in the OEM locations for a hassle-free installation.

Part #: 49-42005

The new MACH Force XP exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4 in. 409 stainless steel tubing for maximum flow; increased horsepower; increased torque; and lower EGTs. MACH Force XP exhaust systems are the perfect combination of performance; fit; and value. All systems use factory mounting locations providing stability and hassle-free installation. High quality OE style band clamps are used for a complete 360 deg. sealing surface. A free-flowing 24 in. 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 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.
