Haven't really thought too much about the catted Y-Pipes only because there is only a few states I believe that will still pass smog with longtubes. I know in California we can't have longtubes period. We either have to change them out, or find a smog connection some where. I would have to look into demand on them first.

I hope your x-pipe will have a nice crossover like the Kook's x-pipe in their TD system. My cheap dumped TDs had a literal X in the X-pipe, they just slammed into each other which I think could affect the way it sounds. I'm betting Kook's sounds better because the pipes come parallel first and have a nice crossover.
Also I think 3 inches and then 2.5 inch over the axle will be fine. Corvettes are all like that.
Thanks
