Hi I've got for sale my like new HKS Carbon/ti catback exhaust. High quality, great sound. I'm asking $690 obo. If you live in socal, you can come pick it up and save some money. email me at yellohead_le@yahoo.com. I've also got a HKS downpipe for sale as well. I had it on for like a day while I was trying it out. I try out a lot of parts...I've used both for less than 20 miles!
