As the title says, I will be adding RB headers and pre silencer to SE. After reading many posts, I have gathered the following information.
Air pump and its muffler = gone.
AVC=gone and covered.
Releif and switching solenoid on the fire wall=gone(cap off these at manafold)
Do I remove the Vacuum switch (loacted on the upper left firewall) that fead through the soleniods mention and cap it off at the manafold?
There are two pipes running to the cat, one is large and seems to be the feed from the air pump (do I cap this?) The other is small and interceps the pipe mid way, Is this the feed for the 5th and 6th ports? (I know the RB pre silencer has a return for the 5th and 6th, is the smaller of the 2 pipes the one I feed this too?

Thanks guys!

 

I left mine in place.... just capped off the ACV

 

Anyone else? I realy need to know what is the 5th and 6th port return is?

 

Can't help you there. I have a 12a and when I installed mine I used the blockoff plates that came with it, but didn't have to worry about any vacuum lines or solenoids. Your car must have a few extra gadgets on it. RB has great customer support, so I'd just give them a call. If you do, please let us know what they tell you.

 

I'm pretty sure you are correct about the smaller of the lines being the one that operates the aux ports.

 

when I did my 85 SE, I did not change anything with the converter tube. 5/6 ports are actuated the same as a stock setup. The small rubber vacuum type hose attaches to the tube then up to your port actuator line. I still have the larger rubber hose clamped to the intake manifold, but it no longer serves any purpose. Make sure the one-way valve is working correctly in the tube. If you CAN blow thru the line from the pre-silencer end of the tube with your finger over the 5/6 port hose nipple, it's bad and should be fixed. There would not be enough back pressure to open your ports if that valve is bad.
