Complete your G8 headers with a matched stainless crossover
Join your Kooks long tube headers to the OEM rear exhaust on your G8 GT or GXP. These stainless X-pipes use 3" front pipework and 2-1/2" OEM rear outlets, with Competition Only or Performance-catted choices for the listed 6.0- and 6.2-litre applications.
SKUs: 24203100, 24203200
An X-pipe for the Kooks header installation
The crossover and rear transitions are supplied together as the front connection assembly. Matching Kooks long tube headers are required, so this is the pipe choice when completing or changing that header system.
Choose the cats for your G8
The Performance-catted option suits naturally aspirated engines. Competition Only supplies the uncatted arrangement for competition use. Both fit the 2008-2009 GT 6.0-litre and the 2009 GXP 6.2-litre applications shown in the vehicle table.
