273 Y-pipe?

Speaking of Waldrons, I purchased a complete exhaust from them and installed this winter. I did not use the Y, and have attached pictures. I decided to get more miles out of my original.

While the rest of the exhaust was great, I did not like the Waldrons Y for a couple reasons, one the bolt flanges were solid instead of pressed, so I would have to use 1/4" longer bolts, and the pipe size was smaller. The OEM pipe on my car was straight and not expanded after the Y. The OEM pipe also was reinforced at the Y, that may be why expansion was not necessary.
