Default LS1 in a Humvee - Exhaust Flange HELP!

Hey crew -

Forgive my first posting being a shameless plea for help; I'm just kinda like that.. I promise I'll contribute all sorts of technical stuff as well as loads of witty banter in the future. So throw me a bone on this one...

Here's the deal: I've just finished swapping an '02 LS1 into a '95 Hummer H1 (originally 350 TBI). I used F body exhaust manifolds because of their high rearward outlet position. Now I need to find a pair of the flanges that connected to them, but of course, buying a Y-pipe to cannibalize the flanges is not an option; because of the attached converters it's just not practical.

So- Does anyone have an old Y-pipe they would chop the flanges (and maybe a short stub of pipe) off, for which I will gladly pay handsomely? Alternatively, is there any source for loose flanges? (Yeah, right...)

Thanks in advance-

John

Why not take it to a local exhaust shop?

I have all my old exhaust (manifolds, cats, Y-pipe,) if you want to buy it

I did- He's the one who said the flanges arent' available aftermarket (who bends a totally custom system to connect to stock manifolds?!?) so I'd need to either bring him some "stubs" off a factory y-pipe, or fab up a pair myself.

Bummer. I could have grabbed them off the donor car too, but thought I would use block-hugger headers and wouldn't need the stock exhaust. DOH!

Thanks-

John
