EGR Valve

Hey guys, I just completed a DSII conversion, and I'm in the process of removing all the unnecessary crap from my engine compartment (I'm waiting to get that done before I post my write up, for those of you that are waiting for it.)
My question is, since I no longer have to pass emissions in my state, can I remove my EGR valve?
My smog pump and my catalytic converter are already gone, so, I was thinking that I could perhaps remove the EGR valve and have one less thing under my hood. Is it do-able and/or worth it? And can I just mount the carb directly to the intake? Or would I have to fabricate something if I removed it?

After the final required inspection on my truck I had it built without the EGR and AIR but I did have a high-flow, 3-way Cat installed. Nothing is lost with one of those Cats. Even without an inspection, removal of the emissions components is technically a no-no though.

Removing the EGR will make the engine run lean at cruise. It doesn't really have any effect on performance, so you should probably just leave it.

Alright. If removing it makes no difference in the way the engine runs, or it makes it run lean, then I see no point in removing it. Thanks, guys!

A functional EGR can actually give a slight increase in the torque of an engine.
With a 300 I6, torque is all we really have, so might as well try maximizing it.
