I just purchased an Invidia Q300 CBE and I have no need for my stock exhaust anymore. I put about 8,000 miles on the exhaust so it is relatively clean and in new condition. I'm hoping to get around $150 for the stock exhaust but am willing to negotiate or look for best offer. I wont go much below $100 though. I live in the Manchester NH area, so if you want to come check it out or just pick it up, let me know!
