if i just take the tube off the cat and weld it up to the racing beat street port presilencer would it have the pressure to operate the 6port actuators? and does the air pump help out with the pressure since it is all conected? im waiting for a gasket to start the project. below i got a pic that shows the pick up tube for the 6port that comes off the air pump tube

The one that RB sells for the GSL-SE says it has the 6 port actuator tube
connection on both the exhaust (single pipe) and street port (dual pipe &
presilencers).

Sounds like you got a 13B street port header and a 12A street port exhaust
setup. Thats the only way I can think it wouldn't have the connections.

Anyway, I think the tube can connect to one of the presilencers and do
what your asking it to do. Unless your throwing a cat in there how do you
expect to pass CA emissions, or is that Central America your from?

Goto RB site and read the descriptions. I can't deep link to the items in
their catalog.

You have C.A. in your description

i live in california bay area so i wont need a smog until next year exactly, i want to leave all the parts on except for the cat so when i do need to get a smog i can just unbolt the exhaust and put the stock stuff back on. i got the full exhaust used so it wasnt meant for the gsl-se. i just got a 02 sensor welded in the headers yesterday now i got to figure the pressure tube.

I just talked to racing beat and they dont have any pics of the street port (duel pipe and silencer) for the gsl-se with the air tube coming out the mid pipe. he did say they sell the tube for me to weld into the mid pipe for the air tube, dood said it has a u shape in the mid pipe to point it towards the engine. So i think i am going to order that tube and some gaskets. Damn i wanted to throw it on this weekend too :/
