(Exhaust) Cat Removal?
The stock rx7 comes with 3 cats on it. Atleast mine does. I know the 6 port actuators need some back pressure my question is how many cats can I remove and still have my ports work. I want some more power but I do not want very loud exhaust.
I really enjoy the quietness of the stock setup how can I gain power without increasing my sound levels dramatically.

you can remove the 2 precats and keep the main cat for your 5th n 6th ports to work, mine still works with no precats and gutted main cat
