Problems of putting a 2.5" Muffler on our 2.25" Stock Exhaust?

I have a Gibson Performance Muffler that came out of my Gibson Catback Exhaust System for my 00 XJ, but I opted for the FM Super 40 Muffler instead, so I have the Gibson just lying around in the garage.

Are there any problems of putting a 2.5" Muffler on my 94 XJ's 2.25" exhaust? I just dont want any ill-effects, such as loss of back pressure thats needed for torque

If there is no problem and the main problem is just getting it to fit, then I'll put it on my 94 XJ and be done with it (assuming it can be welded fine).

Thank you guys!
 
You can get a short adapter pipe to use at almost any parts store.
