If I had better welding skills and equipment, I would fab a HFC. You need to stay legal for Calyfornia. Get a HFC and some mandrel bent SS pipe and weld one up.

If you cut any part of it out you risk not being able to pass emissions.

BTW it is all one part.

It's all one part, after the second o2 sensor, it's simply attached to the flex pipe, the flex pipe could be mistaken for a cat, but it's just simply that, a flex pipe, that allows the exhaust some give.....

Does anyone know if the ST170 cat will work on the SVT?? Could this be the same as a HFC?

No cat at all, and you should have no problem with the sniffer pipe part of emission test. Tac weld the heat shield on to a straight pipe (ORP) and this should pass visual test. These cars are sooo low, and CEL can be fixed with the cheater plug that comes with most ORPs.

don't do no cat. cali doesnt mess around with that stuff.

get a CFM high flow cat or the RT. its legal, it will pass emissions. thats the best way to do it. otherwise you are risking screwing yourself.
