Default LS1 Y Pipe Help?! Swap question

Hey guys,
I need your help. I am doing an LS1 Swap into my LT1 TransAm. However I'm getting stuff for the exhaust to match up. The motor I have, has manifolds, but no Y Pipe. I'm looking at just buying an Edelbrock Header for the motor. I have the Edelbrock Catback already on the car from when it was an LT1. My question is, what Y pipe can I use to make it work, or does anyone have an OEM LS pipe? I'm looking at the SLP Large Diameter one from WS6Store for $183.99 I think this will work right? Help me out....I've went to the dark side, and not lookin back!!

Does Edelbrock make a y-pipe for their LS1 headers? If so, get that.

I would go custom. Take your cats (if you are running them) and Flowmaster collector to your exhaust guy, and have him build the ypipe right on the car. It will be cheaper and easier than trying to find a random one to fit.

Better yet, have custom True Duals built.
