High Flow Cats

  1. Hey Guys, first post here and hope it is in the right place.

    I am trying to source some high flow cats for my car as I have had some trouble finding a donor car with the stock h-pipe and cats. Short of my story but all too common is I bought a car that has a lot of potential but owned previously by a complete HACK! I look up high flow cats in catalogs and such but all have the disclaimer not legal for sale in California. Anyone know of a company that I can turn to for high flow cats that will pass smog?
