2009 Pontiac G8 GXP 4dr Sedan (6.2L 8cyl 6A)
My GXP is a garage queen. 3000 miles after 15 months. BUT it has been slightly modified. Kooks headers, Vararram cold intake, cat delete, SLP supercharger, engine tune and trans tune. It is simply the greatest sleeper ever. A 4 door sedan that can blow just about anything off the road! If you like 500 HP at the rear wheels, this is the way to go. Keep in mind Fly wheel HP doesn't tell the whole story! All these inflated HP numbers are at the Fly Wheel. They made me rate fuel economy. WHO CARES? At this performance level and low miles driven, it does not matter.
