In testing, the down-pipe back exhaust system resulted in gains up to +22 horsepower and +18 lbs. x ft. of torque, as measured on our in-house dyno.
Potential for up to +20 horsepower and +41 lbs. x ft. of torque when combined with aFe's Twisted Steel street down-pipe (P/N: 48-36115-HC)
A free-flowing, transverse muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. The muffler is finished with a high-temp powder-coated black finish and a stamped aFe power logo.
This down-pipe back exhaust system incorporates a factory style exhaust valve which uses the factory exhaust valve motor (not included). The valve helps regulate, direct and control the flow of exhaust gases by opening, closing, or partially obstructing passageways depending on throttle position for maximum performance.
A machined, factory style V-band flange is used for a secure leak-free seal.
This MACH Force-Xp down-pipe back exhaust system uses factory mounting locations providing stability and a hassle-free installation.
Quad 4" Polished Tips
Finishing off this system are quad 4" diameter, polished, 304 stainless steel tips. The tips come with a laser-etched aFe power logo for an aggressive style.
High quality band clamps are used for a complete 360 degree sealing surface.
Brushed 304 SS Construction:
The performance down-pipe back exhaust system is constructed of 3" to 2-1/2" mandrel-bent, brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.
All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
