Not sure which one. I'm guessing 2.25. Could be 2.5, dunno. I think mine is 2.25, and that's a Greddy EVO. What I know for sure is a 3" is for a turbo already. Haven't heard of the WS yet, but a lot of people here have the N1, so might as well go with something tried and true. Sorry if I wasn't much of a help. Not that good with cars..
