Or you can try Mazdatrix

Thats who I orderd mine from.

If you don't care about the environment you can go with no cats here......... Racing exhaust

Yeah, I put the RB header/presilencer combo on my friend's car, and he likes it alot. The quality is top notch.

Um, correct me if I'm wrong...but doesn't Mazdatrix just sell the RB ones? I don't think they have their own do they? But yea...Racing Beat's is the best. Do NOT get the Pacesetters, both the short and long models suck, I've driven cars w/ all 3 different headers...pacesetters(both short and long), and one 88 w/ RB headers...the RBs sound better, feel torquier and are just a LOT nicer.....

You are correct. But RB doesn't sell complete exhaust systems, Mazdatrix does. Thats why I recomended Mazdatrix. You can't just buy a header and bolt it up to your cats.....
