Your WS6 has a line that runs from the drivers side rear corner of the airbox to the AIR pump. You need a 5/8" vacuum cap to put over the nipple on the airbox. If you had the AIR pump recall work done on the engine, you need to cap off the vacuum line that comes off a "tee" on the driver's side of the intake, that also supplies the EGR solenoid vacuum.

Re: aside from taking off AIR pump and lines... anything else?

ok, i dont plan on deleting my EGR. SHOULD i delete for any reason? i have the race headers so there is nothing except the O2 bungs. i was planning on leaving the EGR system alone, but i will get it deleted if i have to i just need to know what needs to be done. what is the number 12 line in this drawing?...http://shbox.com/ci/AIR.jpg
its obviously not gonna work with my headers, so what do i need to do about it. i thought i had everything figured out but now im confused and worried. please help.

Line #12 is the corrugated metal tube that runs from the exhaust manifold to the intake manifold. Since you do not have a place on #8 primary on your headers, you will delete that tube, and put a blanking plate over the back of the intake manifold where it used to connect. You can leave the EGR valve and the vacuum solenoid and the vacuum lines if you want. You can get a blanking plate from:

You have to have the EGR diagnostic deleted from the PCM or you will get an SES light/code. Or, there is a spoof circuit that can eliminate the code.
