Kooks 11-14 Ford Shelby GT500 5.4L / 5.8L 4V 3in x 2 3/4in OEM GREEN Cat SS H-Pipe Kooks HDR Req

This Kooks H-pipe is specifically for your 2011-2014 Ford Shelby GT500 with either the 5.4L or 5.8L 4V engine. You'll get the H-pipe itself, which features 3-inch diameter tubing that steps down to 2-3/4 inches at the outlet to connect to your factory exhaust system. It also includes Kooks' GREEN high-flow catalytic converters, designed for performance and suitable for use with forced induction setups. This H-pipe is built to work with Kooks long tube headers and comes with the necessary clamps for connecting to your factory-style rear exhaust section.

Crafted from 16-gauge T304 stainless steel, this H-pipe is built to last. The material is chosen for its resistance to corrosion and its ability to handle the heat generated by performance exhaust systems. Kooks has been in the high-performance exhaust game for over 50 years, and they handcraft all their products in the USA. This H-pipe has been dyno and race tested to ensure it performs as expected, aiming for maximum power gains. The GREEN catalytic converters are a 400-cell high-flow design, meaning they allow exhaust gases to pass through more freely than standard converters, which can help improve engine breathing and performance.

Keep in mind that this H-pipe is designed to be used with Kooks long tube headers, so you'll need those to complete the installation. The outlet size is 2-3/4 inches, designed to reuse your factory clamps for connection to the rest of your exhaust system, though the clamps themselves are not included. Also, please note that this system is not CARB approved and cannot be shipped to California due to emissions regulations.
