Hello, does anyone know of any aftermarket y pipes that would fit on my 03 6.0 manifolds or shorty headers. I would prefer no cats, and I need them to bolt directly to the manifolds, and both my manifolds have the flat flange. Thanks for looking.

in which truck? if its an 03 NBS you can pick up an off road y pipe with no cats from Pacesetter.
if its an OBS with a 6.0 swap then I am sure one of the other guys will chime in.
It's a 95 obs with the 03 6.0, I have never even seen the original y pipe for a 6.0, I am hoping that I can adapt one to my obs, minus the cats.
Well the 6.0 doesn't really have a Y from the factory. Mine has duals all the way back to the muffler.
your probably going to get some one to make one for you. Or make it your self.
Thanks guy's, yeah I guess I'll build my own, not to mention since my truck lay's frame I don't have much room at all.
I pulled the 5.3/4L60E from a 2002 silverado, along with the y-pipe. I made my motor mounts, and with the transmission in the factory trans mount hole (94 GMC ext cab 1500), I was able to use both the stock manifolds, and y-pipe from the 2002 silverado both un-modified.
it also fits up above the stock OBS trans crossmember as well :) But, since I made my motor mounts, I have 1/2" on each side of the manifold between it and the frame, so I cannot tell you that your conversion mounts will allow you to run it with an unmodified frame.
Thanks for the info, do you have any pics of underneath your truck?
I can get them. I know I had taken some before, but I dont think any where ever focused completely on the y-pipe. I have since then, cut the cats out of the y-pipe, but I can post up some pics once I weld some pipes in.
