I just copied this from my conversation with a guy last night who ordered 3" in 2.5" when our OEM pipes are 2.25" I would think any muffler/exhaust shop could handle the task.

If you get a muffler with a 2.5" out, you will need some reducers to bring it down to 2.25" which is the correct size for our OEM tail pipes.
