Exhaust

I have an 88 Mazda rx7. It is straight pipped right now from the previous owner. I am looking to get the cats back on so it will pass smog in california. My question is do I need to repair all 3 cats to pass smog or just one?

Get a high flow cat and if everything's good on the car you should be fine. You can drop the fuel pressure if you have an adjustable FPR just for the test, that will help.

Magnaflow makes a highflow cat and so does Rotary Performance of Garland Texas.
