Diameter of piping on the Ramus exhaust?

[showaski]

I'm trying to figure out how big the piping is on my Ramus exhaust. I can't seem to find the answer to this question anywhere.

I tried calling RemusUSA, and they didn't have any in stock to tell me the measurements of the piping. Honestly, it looks no bigger than 2 3/4's inch diameter. I'm going to guess it's anywhere between 2.25 - 2.75 inches.

Worse comes to worse, I'll take a string and do the measurements myself. I just haven't had a chance to get under the car and check.

You would think this would be written all over the place as that is the 1st thing anyone should look at when purchasing an exhaust.
