do we need cats in california ? why cant we just put a stright pipe instead of the cat? And can we run true duals in california? people say that you cant because you cant relocate the cats is this true?

 

You need the cats in CA. It's is the law. If you want true duals you'll need dual cats.

Someone should come along any time now and link us to a WWW resource on this topic.

 

there is an emissions law in california,that's why we HAVE TO HAVE cats.

 

Howdy new guy. Go introduce yourself on the West Region forum. I'll meet you there.

 

Cats are necessary to pass emissions, especially in a strict place such as CA. Also, I believe its a large federal fine if you run your car without one. Severly modified exhaust isn't allowed in alot of states (probably CA as well) although I can't tell you the specifics.
