      Improved Performance. Make your powerful Ford Mustang GT perform even better with this Kooks Off-Road H-Pipe. This mid pipe creates better exhaust flow to boost horsepower and torque.

      Race Car Growl. Fit your Mustang GT with this Kooks Off-Road H-Pipe and turn heads with every acceleration. This catted mid pipe creates a low, throaty growl reminiscent of super cars and Indy 500 racers.

      High-Flow Catalytic Converters. This Kooks H-Pipe is engineered to replace your restrictive OEM cat. The high-flow race cats give you more horsepower and torque in the back to boost your performance on the track. As such, this H-Pipe is not CARB-certified and does not conform to California emissions regulations.

      Stainless Steel Construction. Constructed of high-grade mandrel-bent 304 stainless steel, this Kooks H-Pipe is tough and durable. The finish is rust resistant to withstand the elements and holds up against temperatures of up to 1,500 degrees. With an outlet designed to fit your 2.5-inch OEM exhaust, no special connector tubes are needed.

      Application. This Kooks Off-Road H-Pipe is designed to fit 2005 to 2010 Ford Mustang GT models with Kooks 2.5-inch long-tube headers.
