I'm not too sure if this is a good price or not. A guy is selling his aftermarket exhaust and cooler with piping for a jzz30 for 2k EXCHANGE. So i have to give him my stock stuff. The exhaust has 2.5" dumps off the turbos to twin 2.5" exhaust to twin mufflers. The intercooler is 700 230 90 with mild steel piping to suit.
