I'd say it's probably never been done to a Grand Prix before. The rear bumper has been modified for a single center exit that looks factory. Still has the lower valance but the regular exits are gone and smooth to a nice center exit. I haven't seen the car in a while so I hope it still looks as good as I remember it. I also am pretty sure it's just the torque converter, the car took a dump after he decided to do a massive burnout for no reason. And if I'm not mistaken there are codes present as well. I forgot to mention the car has a scanner/tuner mounted in the ash tray area for on the fly tuning. 18s, lowered, and other crap.
