  • Horsepower Increase: +4hp
  • Torque Increase: +5 ft.lbs

True Mitered Merge Collector:

Eliminates dead space that can cause turbulence and hinder flow that formed collectors are prone to produce.

Aggressive Sound:

This system includes dual free-flowing transverse mufflers to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

304 Stainless Steel Tubing:

High grade stainless tubing with a uniform brushed finish provides a beautiful look and high resistance to corrosion.

Mandrel Bent Tubing:

This performance exhaust is constructed of 3" merging into 2-1/2" mandrel bent, 304 stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower and torque.

Simple Installation:

All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:

High quality band clamps are used for a complete 360 degree sealing surface.
