Exhaust piping changes sizes...

Exhaust piping changes sizes...
My "friend" removed his cats and put it in a straight pipe (N/A). However, the possible issue being, the pipe is a different size than the ones it connects to (see pictures). Shown is the front (left side of first picture) and rear welds of the pipe, but the diameter is uniform throughout the pipe (which you can see almost all of).
Is this an issue?
Will it hurt performance?
Etc.

I would guess it's a net gain. I'm not particularly concerned about this as far as engine safety (or something) because I don't think it's damaging anything. I'm just kind of curious as to the effect of it going from a (for example, not sure of the actual numbers) 2.25" pipe to 2.5".

No smog and it's a weekend fun car, but not track or anything. It's likely going back to having a cat on it because sitting in traffic with the windows down on a straight pipe isn't the best situation... always "fun" having it smell like you're deep-throating a tailpipe.
