Greetings all. Been pulling my hair out after a complete overhaul by Rotary Power in Gardena, CA. I was told need rear cat converter or in won't pass smog.
Come to my attention, Mazda doesn't even carry the part I need anymore - I THINK the Mazda P/N is N326-20-500A.
Its the aft cat, mounts behind trans, and has the secondary air injection port on it. Magnaflow doesn't carry them anymore either, so I'm really dead in the water.
Unfortunately, I'll be forded to call the stinking state smog referee on Monday, and see what gives.
Anybody know, if there is a replacement cat converter for this California car, that meets the egregiously overreaching restrictions out here?
Many, many thanks for any input.....

 

I'd recommend the factory main cat. It's heavy duty and includes the split air pipe. I have one I removed from my 69k mile car. If you're interested PM me I'll take some pictures of it.
