I wonder how much it would cost to have a Y pipe made
I was quoted 200 installed at a muffler shop here. Problem is
That's for a crush bent y pipe mandrel bent is much better for flow reasons

Are you having the same issues as i did a few years ago when i installed mine??

The TSP Y-pipe had problems in 2 places... 1) the crossover had about 1/16th of an inch from hitting the 6L80e pan on the bottom and driver side.... and i didnt like that. 2) i had to notch the crossmember on the passenger side where the actual Y merges together and goes over the crossmember. It literally just sit on top of it with no clearance until i cut a bit corner out of it. This was last year or so... so not sure if they may have changed things since then.
