Stock NA exhaust diameter?

[bobbylx]

Anyone know the stock exhaust diameter on the NA 2.3? I removed the precat and and used 2" pipe, but it's a bit too large. I'm thinking its 1 3/4 or something close to that but don't have a tape measure handy and am going to get more pipe when I leave work today.
Thanks

Should be 2"

Yeah it is. Just up near the flange where it bolts to the manifold it's like less than a 1/8 of an inch smaller, I was getting this annoying air lead sound. Anyway, a little extra with the MIG welder and all is good.
