Complete your Mustang header upgrade
Connect your Kooks long tube headers to the factory-size rear exhaust with a purpose-made X-pipe. 11203110 has 3-inch inlets and 2-1/2-inch OEM outlets for the 1996-1998 Mustang GT and Cobra 4.6, with the crossover and clamps supplied together.
SKU: 11203110
Keep the rear exhaust you have chosen
The OEM-size outlet lets you keep a suitable factory-fit rear exhaust while changing the front section for Kooks headers. Match the 3-inch ball-and-socket header collectors to these connections so the joints fit as intended.
Stainless construction for your build
The X-pipe uses 16-gauge 304 stainless steel. It is the uncatted Competition version, providing the front crossover for your competition exhaust without changing the rear connection diameter.
