Hey guys, I was wondering if any of you have an XR8 or FPV GT/GT-P with a dual pipe exhaust modification similar to that of the DJR320. Also any help on were to find this sort or system would be much appreciated, or maybe could this be an aftermarket option that Dick Johnson Racing sell seperatly??? Thanks, Matt PS: We also fitted one of the XR lower front grill from Aussie Car Enhancements! Looks great!!!!
