2 way cats

Hey its my understanding 2 way cats do not need an AIR system or smog pump yada yada, I was wondering if anyone made them for us and if they do well with passing emissions?

You have a "2-way cat" from the factory.... the AIR system is used only for about 3 minutes on startup to heat up the cats faster, and it connects only to the exhaust manifolds. This is unlike the earlier setups used on the 3rd Gen F-Bodys, for example, that first ran the AIR system into the exhaust manifold on startup, to heat the cats, and then switched AIR flow to a connection on the cat, in between the reduction and oxidation beds. Look under your car.... no AIR connection on the cat. yadya yada
