Differences in Y-Pipes/Cats for 96-99?

[Y2KpewterZ]

Found a brand new y pipe on craigslist for cheap. Seller said it will fit any 96+ 5.7 truck. He originally bought it for his Suburban.. just wanted to make sure it will fit on my Tahoe.

I also asked what brand it was, he said he got it from Amazon.. so he says it reallydoesnt have a name brand... but i figure for the price im getting it for (new in box) it will still be worth it.

If your Tahoe is 2000, you won't need the y-pipe... your muffler handles that responsibility just fine (dual inlet, single outlet).
