Ive looked and searched everywhere! My y pipe on my truck is rotting out. It has the 4 inch inlet that the previous owner ghetto rigged together. I would like to try and find a y pipe that is a true five inches. My exaust is five inches all the way back.

 

MBRP might sell you just the y-pipe : they use them in a few of their stack kits.

Well did you ever manage to find your y pipe? I've been looking for a while too..

 

Air Flo Systems has quite a good selection of exhaust elbows and many other truck intake and exhaust accessories.

 

Just about any big truck parts place should be able to get one. I have bought a few of them for our semis from Midwest Wheel, which is one of our area parts places.
