header and y question

I tried a search and could not find an answer. I'm looking for 1.75" headers with a 2.5 y pipe... does any manufacturer make it this way? Only thing I can find is 3" y, thanks for your help.

I have Dynatech's and they are 1 3/4" primaries with 2.5" collectors & y pipe. I believe Stainless Works are the same as well. Not sure about other brands though.

What? No, it's just a stock Tahoe that I want to put headers on. I've read people get worse MPG from headers. So I figured 2.5" y will help with the torque a little and maybe not be too drastic of a loss.
