Attached is an updated NPA for the MACH Force XP and introducing the all new ATLAS cat-back exhaust systems for the 1998-2011 Ford Ranger truck with the extended or super cab. These exhaust systems fit the 1998 to 2011 Ford Ranger trucks with L4-2.3L, 2.5L or V6-3.0L, 4.0L engines. In testing, these systems produced an additional 7 horsepower and 9 lbs. x ft. of torque as verified on our in-house dyno. These cat-back exhaust systems are constructed using 2-1/2” inch mandrel-bent tubing that uses the latest in manufacturing technologies, resulting in increased flow and performance. High quality band clamps and an OE style flange are used for a complete 360-degree sealing surface eliminating leak paths. A stainless steel straight through designed, free-flowing muffler is included in the Mach Force XP system to absorb high pitch tones producing a powerful sound and unleashing all the available horsepower and torque. A 2-layer aluminized steel chambered muffler is included in the ATLAS system for an aggressive tone without droning. Both systems feature a high luster 3-1/2” inch polished, 304 stainless steel, rolled tip for an aggressive style. These are 100% bolt-on systems that retain all factory mounting locations and includes all necessary hardware for a hassle-free installation. Order Now!
