JAMO Performance Exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4" 409 stainless steeltubing for maximum flow, increased horsepower, increased torque and lower EGT’s. This system is available in 4" turbo-back with a highly polished muffler featuring polished welds to provide a seamless appearance, and a stainless steel tip. JAMO Performance Exhaust systems are the perfect combination of performance, fit and value.
All systems use factory mounting locations providing stability and hassle-free installation. 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. High quality OE style flange and U-bolt clamps are used for a complete 360 degree sealing surface.
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. With a free-flow design, the strategically placed louvers provide sound deadening control for a more pleasant in-cab ride.
