3.1 exhaust pipe size

[93CutlassSupreme]

ok, can anyone verify for me the size of the exhaust pipe on a single exhaust 3.1 Multiport, going into and out of the cat?

 

i've heard 2.25" on here, just want to be sure before i buy the pipe.

 

thanks.

I'm pretty sure it's 2.00" At least that's what I've been told in a similar post to your own last year.

The straight pipe I have in place of the cat is 2.5" and it welded up perfectly. Although I'm pretty sure the factory piping is 2.25".

Where was it that you measured 2"?

in and out of the cat.

 

 

slightly flared 2.25" pipe just barely fits over the stock pipe.
