passenger side #2 pic can i jus close off that silver hose? or does it need to stay open?
on passenger side #1 pic can i leave it like that? or does the lower silver hose need to be open ? and on the driver side can i take that black hose out and close up the 2 tubes it goes too ? please any help would be great.

 

Yes, the tube down the firewall feeds air to the cat con, you can plug it off or plug it at the cat and remove the tube.

On the headers/manifolds, remove all thehoses and check valves and cap off the npt thread on the air tubes, much cleaner.
The check valves are the black things, they uscrew easily. hardware store will have proper NPT caps.

 

k so passenger side 2 pic i can jus remove that silver line? and on passenger side 1 pic what about the silver tube above the manifold tubes can that be plugged up too or does it stay open? and i know to cover the manifold on the driver side but what about the other silver tube towards the back on that side where the manifold attached too? do i plug that also or keep it open? i jus wanna make sure i don't plug anything i'm not supposed too.
