Question Stock exhaust tubing diameter

Can anyone confirm for me that it's 2.25" and not 2.5"

I've been having a hell of a time trying to find out and it's keeping me from ordering my electronic exhaust cutouts. Thanks!

This is what I found when I took the plunge in modifying my oem exhaust,

Kleemann Cats 3"
Supersprint/Carlsson Xpipe 2.75"
stock pipes 2.5"

Now I'm confused....because I called supersprint, and they didnt know the stock tube sizing, but told me that their xpipe for my car was 2.5" "oversize" tubing, so he thought the stock would be 2.25".

Is it possible that your car has different exhaust since your emissions requirements are so much different?

So the exhaust is 2.5" along the entire length of the system?

From the manifold back, I'd bet on Mo's numbers being reliable since he has actually fitted the parts he is talking about.
