Testing: In testing, the axle-back exhaust system produced a max gain of +4 horsepower and +4 ft. lbs. of torque verified by our in house dyno. Potential for up to +24 horsepower and +27 lbs. x ft. of torque when combined with aFe's Twisted Steel street Tri-Y headers/X-Pipe (P/N: 48-34127-YC). Aggressive Sound: Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. Exhaust Valve: This axle-back exhaust system incorporates factory style NPP dual mode exhaust valves which use the factory exhaust valve motors (not included). The valves help regulate, direct and control the flow of exhaust gases by opening, closing, or partially obstructing passageways depending on throttle position for maximum performance. 304 SS Construction: The performance axle-back exhaust system is constructed of 3" mandrel-bent, 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking. Simple Installation: This MACH Force-Xp axle-back exhaust system uses factory mounting locations providing stability and a hassle-free installation. Quad Polished Tips: Finishing off this system are quad polished, 4" diameter tips. The tips come with a laser-etched aFe power logo for an aggressive style. Leak-Free Seal: High quality band clamps are used for a complete 360 degree sealing surface. Note: This system only fits manual transmissions models without AFM valves.
