aFe Power, Mach Force XP Hi-Tuck 2.5" CAT Back Exhaust, for 07-11 Jeep Wrangler Unlimited JK 4 Door with 3.8L

The aFe Mach Force XP High Tuck cat-back systems are designed for maximum ground clearance and performance. These aFe systems are finished off with a Hi-Tuck tip that is dumped right behind the rear axle which was developed to give your Jeep extra clearance during extreme angle climbs or descents. A straight through design, free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all of the available horsepower and torque from your rig. Mach Force XP exhaust systems are constructed of 2.5" mandrel bent stainless steel tubing with smooth transition bends, which allow for lower turbulence, increased horsepower and torque while improving throttle response. The Mach Force XP 2.5" system delivers up to 7 additional Horsepower and 9 ft/lbs of torque. The Mach Force XP kits also use all factory mount locations providing stability and a hassle-free installation. The OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. High quality OE style flange and band clamps are used for a complete 360-degree sealing surface eliminating leak paths. All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
