i wish there were arrows pointing at things in those pics. they get some what confusing at times. id also like to know how many of what size nipple covers i need.

You need map sensor, fpr, and bov. The rest can be eliminated.

Just remove the CAS and you won't have any problems with those emission devices.

thanks guys i got it everyone helped alot

Depends on what you mean by "emissions", most people lump a lot of engine components into the "emissions" category, like the BAC, air bypass solenoid valve, air supply valve and thermowax, though they are of a separate and distinct system. It's common to see things removed for no reason and even more common to see a mess of problems after attempted "emissions" removal.

Based on your actual needs and intents you may remove/retain various components of the secondary air injection, emissions or twin scroll control; it all depends on what you're doing. I recently deleted my air pump, ACV, sub zero start assist, twin scroll control, split air pipe and EGR as well as the entire rats nest and associated solenoids. I found some use in the diagrams below but adapted them to suit my own needs.
