I have a 01 2.5RS SPT cat-back exhaust for sale. It's about a year old with some heat damage on the mid pipe, other than that it looks and sounds great. It's the perfect exhaust system if you want to give your RS some attitude. I have had no cop trouble (no exhaust tickets) when the system was on my car. I bought the cat-back at Mastro Subaru. Im asking around $100 for it.
PM me if you are interested.
