X-Pipe 2.5" vs 2.25"

I've read (in many treads) where you all seemed to have used both of these sizes x-pipes for your mid-muffler delete. I'm guessing both will work with some exhaust work or is there a clear answer on pipe size?

2.25 is the same diameter as factory and is what I used. 2.5 is close enough to weld. It doesn't matter I just chose to go with consistency.
