Kooks 07-10 Ford Shelby GT-500 5.4L 4V 3in x 2 1/2in OEM GREEN Cat SS H-Pipe Kooks HDR Req

If you're looking to unlock the full potential of your 2007-2010 Ford Shelby GT500, this Kooks H-pipe is a critical piece of the puzzle. Designed specifically for the 5.4L 4V engine, this system is built to maximize exhaust flow, which directly translates to more power and a more aggressive exhaust note. Kooks has been a leader in performance exhaust for over 50 years, and this H-pipe is a testament to their experience and dedication to quality.

This H-pipe is constructed from 3-inch, 16-gauge 304 stainless steel, chosen for its strength and resistance to corrosion, ensuring it holds up to the demands of a high-performance vehicle. It features Kooks' own GREEN catalytic converters, which are 400-cell high-flow units designed to improve exhaust scavenging without significantly restricting flow, even with forced induction setups. The system uses a ball and socket connection to mate with Kooks long tube headers, and the 2-1/2 inch outlet is designed to connect to your OEM exhaust system, reusing your factory clamps.

Keep in mind that this H-pipe is designed to be used exclusively with Kooks long tube headers, so if you don't already have those installed, you'll need to add them to your build. This system is not CARB approved and cannot be shipped to California. It's a well-built component from a company with a long history of racing success, handcrafted in the USA.
