exhaust problem

I was wondering if anyone new the piping size for the stock exhaust on a
92 prelude si. Because I want the n1 exhuast made for a turbo.
But the piping is 80mm will that screw anything up or will it be okay.
Because I like the 115mm tip on the turbo one.

just take it to a midas and have them weld it with an adapter for 15 bucks

weld what part with an adapter? by the cat or the muffler?

If you are keeping the cat, it should be okay. Apexi designs their catbacks to bolt right up to stock hangers and cats.

thanx, you mean the stock cat right?
