1997 Camry 4cyl, what exhaust inlet

Hi,
I'm going to install a new performance muffler on my '97 4cyl Camry soon, but I was wondering what inlet size I should get the exhaust. Do they make exhausts to custom fit (bolt on) for my Camry? That would be preferable, then I wouldn't have to pay to get it welded on. If not, what size is the outlet of the pipe before the muffler on this car, and what inlet size should I get on the muffler?

Thanks,
Marshall

you can find a direct fit one mine is from TRD but, there tough to find and expensive.
