I've got the stuff from the manifolds to just before the cats...

Lemme know what's up.

I could use the flanges that bolt to the manifolds if you can cut them off a few inches back. I want to build a set of cat bypass. My current pipes from the manifolds are custom built with the truck flanges and then adapted to camaro converters and then the camaro quick connects bolt the individual cats to the main pipes going to the rear. Salvage yards around here won't sell the flanges for some reason even though they can't sell the cat assembly per smog laws.
