1500 vs 2500 Y pipe

[dwrestle]

I was just wondering if the 2500 trucks with the 350 have any different Y pipe than the 1500 trucks?

Both of those are from Vortec trucks. Talking Y pipes I'm assuming he's talking about TBI trucks.

I am not sure about the differences between the 1/2s and the 3/4s. The only thing I do know for sure, is the 3/4 Van Y pipes are factory 3".
