Choose the connections for your G8
Use matching Kooks connection pipes or a full exhaust. The application covers the 2008-2009 GT 6.0 and 2009 GXP 6.2, with the detailed vehicle rows retained for comparison.
Align the full exhaust during fitting
Professional installation allows the headers, crossover and rear exhaust to be positioned together. The installer should check the dipstick, steering-shaft and wiring clearances, followed by the joints after a heat cycle.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your headers, complete exhaust and fuel. Talk to us to discuss tuning for your vehicle and the parts you are fitting.
Matching products
For the 2008-2009 G8 GT 6.0 or 2009 GXP 6.2, add the G8 GT / GXP X-pipe to join these long tube headers to the rear exhaust.
