1985 exhaust system(RB street or stock-port + CAT)
I can choose 2 exhaust systems. 1985 stock-port and street-port exhaust system. I got a stock-port engine.
Does the street-port exhaust system give me more performance?
Can I use a CAT with these 2 exhaust systems?

Airflow is my life
If you dont plan to port the motor, then get the stock port system. Not sure, but the stock port headers might mate with the cat, but then you cant fit the presilencer in. Call Mazdatrix and ask.
