I would like to see a pregen with the GXP setup... but overall the GXP sits to be the nicest riding Grand Prix made.... The ride, the interior, the quickness, the sound... its endless. I have magnaflow exhaust with the K&N intake, which was how I got it from the dealership! Turbo... Wouldnt even want to do that with the trans in these cars... otherwise the LS6 cam swap with 1.8 rockers seems to be a sick setup. Cant want to hear more plans from you guys here.
