Stock exhaust pipe size

What's the stock exhaust pipe size on a 87 N/A 5-speed RX-7? Is it 2 1/4 going into the catalytic converter or 2 1/2? Looking to replace the stock exhaust system.

I do believe it's only 2" (MAYbe 1 3/4")...I forgot to measure and I threw the stuff away already. But remember it's got lots of crush bends in it so it's not uniform (aka...crap).
