2.2 L61 Exhaust Size

Hey.. I know this is most definitely a repost and has been answered before, but my browser keeps freezing when I try to use the CSS.net search.
So.. what is the exhaust diameter on the 2.2 L61?
When I google'd it, I found a site that claims it is 1.75", but that seems small to me and I just wanted to double check..

Do you see any problem with using a 2.25" electronic exhaust cut out and just welding it on using two 1.75" to 2.25" exhaust reducers? I'm just not sure if it would cause any back pressure problems when I open the cut out.
