That will work for your car but there are a couple of things to make note of about it. First of all it is the header that goes to the "true-dual" Racing Beat system. You can see the whole system on Racing Beat's site. The other thing to be aware of is that that one does not have a pickup tube for actuation of your auxilliary ports.

EDIT: It looks like that it is the full race version of their "true-dual" system because I cannot see an O2 sensor bung on it either.

 

could i just wire them open

 

Yes.

 

You could wire them open but as it has been covered many times before, you will lose a little power on the low end of the RPM range. A better solution is hook a small airpump up to the auxilliary port actuators that is controlled by an RPM switch. There are instructions below if my link is still valid...
