Product Details
Kooks Headers has been a name in high-performance exhaust for over 50 years, known for crafting parts that win championships and set records. This 2-1/2 inch catted X-pipe is built for your 1999-2004 Ford Mustang GT or Cobra with the 4.6L engine. It's designed to connect to Kooks Headers with 2-1/2 inch collectors, helping your engine breathe better and potentially improving its sound and power.
This X-pipe is constructed from 16-gauge T304 aircraft-quality stainless steel, which is a well-built material that holds up well over time. It features a ball and socket style connection to ensure a solid seal with your Kooks headers. The X-pipe design itself helps to merge exhaust gases from both banks of cylinders, which can lead to a smoother exhaust flow and a more aggressive tone compared to stock. It includes high-flow, 400-cell catalytic converters, designed for performance, though they are not CARB approved and cannot be shipped to California. The outlet is 2-1/2 inches, designed to connect to your OEM exhaust system.
Keep in mind that this X-pipe requires Kooks Headers with 2-1/2 inch collectors to ensure proper fitment and function. It also comes with clamps for installation. Kooks backs their products with a limited lifetime warranty to the original purchaser.
