Where to get a 87 R-10 Y-Pipe?

[eddieeddieg]

I have true duels w/o cats on an 87 R10
and I'm looking to replace it with a stock exhaust.
(I bought the truck from a non-emissions county)

But I'm am having trouble finding a replacement
y-pipe. Junk yards are unable to find one either.
Also talked with the local GM truck folks
the pipe has been discontinued.

I have been to the local muffler shop
and they want $325 to build a y-pipe and install
a cheap cat & muffler.

Any ideas who would carry one.
Maybe you just installed duels
and you have one laying around?

Thanks
