that should do it.

The main cats just don't hold up. You are in NJ, they mandate the "CA standard" cat. If so, don't complain about the cost, it's a much better can than the basic replacement. It will last a long time... it has to meet OBDII durability standards. It might be more expensive, but it will 3 or 4 times longer.

Maybe it's just me :-) but I'm confused

Says only not for sale in CA, nothing about NJ. Most other sites list this and other cats (e.g. Catco) as being "49 state legal".

Is this cat not legal in NJ? or is it just not as good?

One more ? do I need to worry about the pre-cats or if I replace only the main should that do the (emissions) trick?

Thanks all!
