RB Header/Presilencer
I'm looking to pick up the rb header/presilencer combo... I was wondering which cats it replaces (if any) and if i'll still pass smog tests... Has anyone bought this combination? Were there decent power gains? I have an NA 87

Ok, first and foremost, you cannot run cats w/ just the header and expect it to bolt right up. The header is longer than the precats. Don't order one w/o ordering the other. I have both, and you should expect a very substantial gain. And no, you will not pass smog.

Great thanks... is it possible to get the RB headers and an aftermarket cat? Its kinda vital for me to pass smog tests that are coming this summer in my city.

Just save your old setup, and swap it back in each year. Racing Beat claims that www.mazdatrix.com sells a cat that will botl up to the header and cat-back. Good luck!!
