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.

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.
