first off i just wanted to give props to 85 SS 302 Coupe. And also for 500 bucks you can get alot. i got my 17" 077s, off road x, flowmaster catback and underdrives for a total of $148. (Sold old 17"s for 325, traded old catback for a PS2 and sold that for 200, got underdrives off ebay for 38, sold old h-pipe for 75.) doesnt get much better then that, do far the only thing i paid for with my own money is the xpipe and the soon to be gears
