What's the diameter of the stock exhaust pipes of a 4th gen Max after the cat?

I was just wondering... if the y-pipe dumps into a 2.5" flange... and the cat's only 2", isnt' there a restriction? Thanks.

This should explain it:

There are a couple of good links in there.

 

Thanks Bill, I did the search earlier and nobody seems intersted in the threads on what the stock diameter is, just that bigger is better....

From the threads, it looks that 2.25 to 2.5 is optimal for a normally aspirated Max. But I was wondering as to the gains as well, since in most of these, people are changing different components with different. I tried to measure the pipe at the flange for my stock muffler, but can't tell if it's 2", 2 1/8" or 2 1/4" because I don't know if I should be measuring the outside diameter, inside diameter, etc... Thanks.
