OE style hangersare used to maintain a stable pipe location during high vibration and high heat conditions. High quality OE style flange and U-bolt clamps are used for a complete 360 degree sealing surface.


  • A free-flowing 30" 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.
