Alta catback question

Does the Alta catback exhaust retain both of the original cats? What is the 4th picture on this description:

Is it a replacement for the 2nd cat?

Its a resonator, the first cat is very close to the turbo, the other one is a bit upstream of where the catback connects to. No, this does not replace any of the cats.

Great - that makes it a legal upgrade for SCCA G-stock class.

from my days with the miata there are about 4 or 5 autocrosses a month around florida. I usually look at miata.net in the southeast section they post a monthly thread with all the autocrosses

That is correct! Keeps both cats and we will offer our downpipe with two cats later this month in 3" as well to compliment. Check out my installation here:
