Product details
Introducing the new aFe Power MACH Force XP dual exhaust system for the 05-09 Ford Mustang V6-4.0L. In recent testing, this system produced 12 horsepower and 16 lbs. x ft. of torque. This exhaust is constructed from 2.5in. mandrel bent, stainless steel and is MIG-welded. Dual high flow, stainless steel, single in, single out mufflers are used to maximize performance across the power band while maintaining a great tone. To finish off this exhaust aFe uses dual, laser etched, 3.5in. polished 304 stainless steel tips. Note: The V8 rear bumper cover is recommended (Ford OE Part Number 5R3Z17K835BAA). The use of the OE V6 bumper cover requires cutting and should be performed by a skilled technician.
