Hi, I'm looking for a pair of the flanges that connect to the outlet of ls7 exhaust manifolds. This flange is welded to the cat converters. I don't need the cats, just the flange and ideally the o2 sensor bung.
I know tabtech makes the flanges but I believe they lack a recess for the gasket to sit in... plus having the part where it goes from that flange to a round pipe would be nice.

Thanks!
