Well im planning on removing my emmision controls on my 87 rx7 non turbo . My question is if i remove that stuff , will my actuators open for the secondary intake ports.

 

REPOST !!!

Everybody says that on s4, the auxiliary ports open thanks to back pressure from exhaust ... There's a pipe that goes goes from the main cat to the auxiliary ports for that.

You can see that in this page (near the bottom):

Nope, get a racing beat presilencer, that will solve your actuator problems.
