Hammerhead, if I read correctly you had the GMMG I pipe that connects to the Y expanded to fit over it? This would give it an ID of 3"? Did you have it expanded at an exhaust shop? Thanks.
The indication I got from reading and talking to people is that this area did reduce to something smaller than 3" OD and is why I made the comment.

Yea, I had the GMMG I pipe expanded to fit over the 3" AR Y. I tried stretching the I myself the first time with an exhaust expander and it cracked. I had the shop that installed my bullet hook it back up. In retrospect it was kind of a PITA, but there's less of a bottle neck there now.

I opted for the 3" outlet on my Y pipe. ARH will weld a 3" end and all you have to do is go to a muffler shop and have it expanded. Talk to Nick at A.R.H. He is a big help.

Might be a silly question but why don't they weld all the way around the primaries at the flange? I notice some headers do and some don't weld all the way around. Seems like that'd be like putting 3 lugnuts on instead of all 5.

I remember when you were trying to decide on what to go with and were asking for advice. Glad you're happy with your decision...you definitely made the right choice.
Great gains as well! I picked up 19/27 on my car completely stock with the ONLY change being the AR Headers and catted y-pipe through a 12 bolt.
They are welded all the way around the primary on the head side of the flange.
