Ok I have an 84 GSL-SE that the owner before me put a header on with no way to open the 5&6 ports so I am looking for suggestions my first idea to fix it would be to tap a line into the header to route some exhaust to the solenoids for pressure, but I would like not to put any un-necessary holes in the exhaust if I dont have to. The second thought I had was to just remove the 5&6 sleaves and run them open but I don't know how this will affect bottom end performance, start up, or driveability. Any feedback from people who have performed either of these mods would be appreciated

To clarify what I meen is a header and no cat, which normally the can has an air feed tube to actuate the ports

you will need to install a pressure tube from the exhaust to the port tube. the ports open from back pressure from the exhaust and are fully open above 5500rpm. why not install a presilencer after the header that is made for the SE specifically and it will have the tube and flange installed already. you can then use your original pressure tube.

when i did mine i hooked the 6 ports up to the factory air pump. add in a valve and you can adjust the opening point.

you can wire them open but it sucks

Yeah I will have to look more closely to sone diagrams I am not sure what all is hooked up to the air pump and what is not
