I am looking for a stock cat-back exhaust system for a WRX. I am willing to trade my HKS Hi-Power, (plus a little extra cash), for it. If there is anyone living in the bay area that would be willing to drive to my location to exchange exhausts please let me know. I will probably have you meet me at my mechanics shop where the exhausts will be swapped. I will take care of all installation fees, so you will have your new exhaust put on for free. If interested, please email : costanza@sonic.net
