inlet size for tips....

Maybe your 97 is different but before I purchased my tips for my 02 I measured the pipe right at the back of the factory tip and it was 2.25". The tips I purchased were 18" by 3.5" chrome angle-cut tips with 2.25" inlet and they fit perfect.

As mentioned, the stock tubing is definitely 2.25. Aftermarket catback's are 2.5. I wouldn't stress the new tips inlet so much though.. a good muffler shop should have no trouble welding a 2.5 inlet tip to a 2.25 pipe. I've had it done on other Mustangs.
 
Either way your safe. If you for some reason had a 2.5 inch pipe, and a 2.25 inlet on the tip, the beginning of the tip could be cut where it begins to flare. Vise versa, your could weld a small piece of 2.25 pipe with the end flared outward to meet with the tip (there is a machine that does this but I don't know what it's called). I've also seen my muffler friend take a thin metal rod he welds in between to fill gaps from different pipe diameters - I'm not sure if that makes sense, but I don't know how else to explain it without pictures. :) Point being, a muffler shop can do it.
