The short answer: No.

I just checked the parts numbers for the cats on Mazdatrix, and it looks like the second and main converters in both the 84-85 12a and 13b engines are both the same, but the first converter is different. Racing Beat's aftermarket exhaust equipment is completely different between the two, other than the mufflers.
