I think skunk2 mega power catback has a 2.5" version..
In japan maybe RS*R..
Custom all the way! If you know of a reputable company that will do custom exhausts then go for that, guaranteed full stainless steel exhaust, usually a life time warranty and way cheaper than brand names!
i am not doubting skunk2 or buddyclub exhausts as I have had both and they were good but my custom system is best so far!
