My fathers auto shop does custom exhaust. Honestly 2.25 is plenty for the little motor. 2 is more than enough even. Im not sure that it has 2.25 factory but it may.

It has 2 inch diameter piping stock, iirc. I used to have a 2.25 Magnaflow catback when I still had my P5 and that's more than enough flow for a no-turbo car.
