From what I have read, Kooks are about the best for fitment and overall quality, but they ain't cheap. Your profile says you are in "Branford" but it doesn't say what state . . . if that is Branford, Connecticut then I believe you have emissions inspection and you need working catalytic converters to pass. The Kooks "Green Cats" are supposed to be some of the best, that give the best chance of passing in "Green States" like Connecticut.
