Well I currently have an Extreme PSI downpipe and an electric exhaust cutout welded in after that. I found a good deal on a Greddy Evo catback, and am looking to purchase it. My downpipe, which also replaces the cat, necks down to bolt up to the stock catback. I don't believe that the evo I am buying comes with the adapter to bolt to the stock cat. So I need to know where I can purchase one of these. I couldn't find anything on summit, I may try to post a wtb ad on the trader, for anyone that doesn't need theirs. TIA
