No way in hell would i pull over for those. No way my GTP could run from the Cobra, but if the 350z didn't have much done to it, I could at least be far ahead enough he couldn't pull up next to me to tell me to pull over. I'd probably run until they brought out a marked police car.
As far as the illegal equipment goes, it could be something as small as exhaust, but i'm sure i was more than that, since he said $10 grand and all
