Well I just had a STI uppipe and full turbo back installed, flashed to stage 2 and my clutch started slipping

So I'm trying to sell some stuff to pay for the $1,000 clutch install bill, including the autospeed catback I just purchased from mk6933 (which sounds incredible). The previous owner installed a magnaflow glasspack to cut down on the volume and droning. Very deep sound. No tinny or raspy sounds whatsoever. The exhaust itself is in very good condition, has a few scratches on the bottom of the mufflers, but the tips are in perfect condition. The catback is still on my car, but will be coming off when I get the clutch installed on monday. I'm willing to take a little bit of a hit on what I paid for it. Looking for $500 picked up. I'm going to give local buyers a chance first. Located in the chicago burbs.
