Exhaust decision
I have a 1988 turbo rx-7. I have the bonez turbo flow system consisting of a high-flow cat and a 2.5" downpipe. Should I go with 2.25" piping from the cat to the mufflers or 2.5"?

don't use the 2.25 before the split... especially since you have a 2.5 inch down pipe... go with the 2.5 from the cat to the y-pipe!
