there is a guy that has been talking quite a bit of crap about my friends car and says he is going to hand him his ass when he gets the chance. The guy drives a 2006 GTO that has exhaust and other than that i don't know, since i've only seen and heard him driving down the road. My friend has a 96 cobra with a vortech s/c @9psi, full bolt ons, aluminum driveshaft, fmu, dyno tuned, 3.73's with fully built rearend he is putting down around 430rwhp last time on the dyno........so my question is what kind of mods would this GTO need to have to beat him?
