Thanks Mista Bone...

Looks like the HF uses an exhaust manifold that is similar to the non-Cali manifold in the VX. The design of the cat is different enough that the Cali cat will not fit with the non-Cali manifold (gasket is flat for the non-Cali cat, round for the Cali cat).

I do see the later CX/DX/LX have a similar manifold/cat arrangement, but the engines are 1.6l vs my VX's 1.5l... would the exhaust ports and studs be the same? Also, it looks like there are two O2 sensor ports (guess I could plug the lower one) and the flange from the bottom of the cat to the rest of the exhaust system looks different. Obviously, I'd love it if the later cat would work on my VX, but want to make sure it works before shelling out big bucks... even used ones are pricey!

I wouldn't mind finding an all-in-one manifold & cat, but everything I've found so far says "Not legal for sale in CA!"
