2.25 will suit your needs.

As kind of a stupid geralization, 2.5" pipe is good for around 250hp N/A motors. My d15b8 only has 70hp, so I don't think 2.5" is gonna help anything. I do have a 2.5" on my 94cx with the stock d15b8, and it drives fine, but I only have because I'm planning a type r swap...
