Kooks 11-14 Ford Mustang GT 5.0L 4V 3in x 2 3/4in OEM Exhaust GREEN Cat H Pipe Kooks HDR Req

Starting with 3-inch diameter tubing that steps down to 2-3/4 inches at the outlet, this Kooks H-pipe is built from T304 aircraft-quality stainless steel. This material choice means it's well-built to resist corrosion and handle the heat from your 5.0L 4V Mustang GT's exhaust system. It's designed to connect to Kooks long tube headers, and the GREEN catalytic converters are high-flow, 400-cell units that are suitable for use with forced induction setups. This H-pipe is specifically made for the 2011-2014 Ford Mustang GT, ensuring a direct fit with the factory exhaust system at the rear using the OEM clamps.

Kooks has been in the performance exhaust business for over 50 years, and this H-pipe is a result of that experience. Every product they make is dyno and race tested to ensure it performs as expected, and this one is no exception. The system is designed for maximum power gains, and the included catalytic converters are engineered to help reduce emissions while still allowing for improved exhaust flow compared to stock. This H-pipe is handcrafted in the USA, reflecting the company's commitment to quality and domestic manufacturing.

Keep in mind that this H-pipe is not CARB approved and cannot be shipped to California. It's also important to note that this part requires Kooks long tube headers for proper installation. The 2-3/4 inch outlet is intended to connect to your existing OEM exhaust system, reusing your factory clamps, which are not included with this kit.
