If you are looking for a highly engineered Downpipe, look no further than the aFe Power Mach Force XP Downpipe. On a chassis dyno, this Downpipe produces 14 horsepower and 39 lbs/ft. of torque at 1900RPM and is constructed of mandrel bent, brushed 304 stainless steel tubing and flanges that mount to all factory mounting locations.

This system uses a unique resonance chamber to capture sound waves and minimize in-cab resonance producing an aggressive tone on throttle with a smooth sound at cruising speeds without effecting performance.

This Downpipe is 100% TIG-Welded and uses a stepped design that increases exhaust velocity and eliminates low pressure drops which helps to scavange the exhaust for increased intake charge and more power.
  • 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
  • A unique 3.5" to 4" stepped design, popular with race headers is used to increase exhaust velocity and increase usable torque. This means more aggressive throttle response and increased passing power.
  • This Downpipe is constructed of durable CNC mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.
  • This Downpipe is designed using a resonance chamber to help reduce the in-cab resonance found with other Downpipes.
  • Hassle-Free Installation - All hardware and brackets are included for a hassle-free installation.
