This axle-back exhaust system incorporates a factory style exhaust valve, which uses the factory exhaust valve motor (not included).
The valve helps control, regulate, and direct the flow of exhaust gases by opening, closing, or partially obstructing passageways depending on throttle position for maximum performance.
This Mach Force-Xp axle-back exhaust system uses factory mounting locations, providing stability and a hassle-free installation.
Finishing off this system are dual 4" diameter, gloss black, 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, ensuring a leak-free seal.
The performance axle-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.
