A 3-inch crossover for your GT500 exhaust
Connect your Kooks long tube headers to a matching 3-inch rear exhaust with this GT500 Race X-pipe. 11323120 keeps the inlet and outlet at 3 inches, for the listed 2007-2014 Shelby 5.4 and 5.8-litre applications.
SKU: 11323120
Match the rear exhaust diameter
The 3-inch outlet suits a matching aftermarket rear exhaust. The front uses the 3-inch ball-and-socket collector on Kooks headers, so check both ends when choosing the exhaust sections.
Crossover and clamps supplied
The uncatted Competition X-pipe is made from 16-gauge 304 stainless steel and includes clamps. Have the installer align the headers, crossover and rear exhaust together before tightening the joints.
