No EGR what can i remove ?

I suckered you into a multitiude of questions please help me understand a few things...

Without the EGR (stealthram) i should not be able to pass ye old emmisions test as far as i know plus the fact that i have afr 195's which arent emmissions legal as far as i understand so i can remove the vac junction next to the coil on the passenger side....correct ? of course ill need to plug the underside of the throttle body, and the other lines comming out from the vac junction, but isint there one vac line that goes to the cruise ?

My second question is dealing with CATS and A.I.R. If i remove the AIR and the tubes but leave the pump or get a idler pulley and tune for the loss in fuel pressure (per what joe said on another post) with my stealthram, will i be fine as far an engine drivability is concerned ?

My car is a summer only car, and ill probbably just register it somewhere where emmissions is not req, im almost tempted to gut the cats too, do you think all this is a good idea considering my motor and supercharger, mods below ?

Oh one last thing i have the edlebrock performer headders with the air hookups, i can just plug those if i remove AIR right ?

THANKS guys !

take the cats out, air tubes out, u dont need to get a smog pump pulley, just take it out and get a biggger belt and reroute it, or u could get the delete pulley to make things easier its up to u.

u can cap air tubes off of the headers no problem, u can find the caps u need at local hardware stores i believe.

yeah if u wont need emissions just delete the cats, all air stuff, and all erg stuff.

i would if i could.
