F250 351w 'to emissions or not to emissions'

This is my first post here!

The truck is a 1992 F250 5.8L AT 4x4

I was taking off my leaking EM to replace with some shorty headers, and broke 2 of the 8 bolts . That sucks, but while taking off the inner fender plastic to drill out the broken bolts it started me thinking. Does the airpump and all it's associated hoses, and the cluster f*ck of valves or solenoids or whatever they are on top of the engine need to be there? What are the pros and cons of taking it all out or is it not even an option? I'm in NH, so '96 and older don't get emissions tests, I would rather not have to deal with any of it if it failed in the future and I don't care about the environment so...

For that matter, what about removing all the emissions related stuff? I saw an EGR eliminate mod on a website: http://fordfuelinjection.com/index.php?p=61

Any suggestions?

Keep the EGR, unless you're really worried about 5hp. I've seen too many people (including myself) run into endless problems after removing EGR... however, you could disconnect the hose running from your exhaust to the EGR valve and that will do fine. Leave all the other sensors and vacuum lines in place on it.

As for the smog pump: ditch it. All they do is make lots of noise when they get old. You'll need to find a way to plug the holes in your exhaust, but it's worth it to get that thing out of the way.

...and don't waste your time/money on a smog pump eliminator, either. Go to the parts store and get a shorter belt.

New belt: $11.95
Smog pump eliminator kit: $69.95 (and tacky-looking)

I'm not concerned so much about gaining hp as making it run smooth and getting rid of potential problems/annoyances before they happen. When taking out the EM's I had to take off part of the smog pump hoses anyway. THen I realized that the instructions for the headers said it was for models without smog pump, so I'm killing 2 birds with one stone!

The EGR eliminator I was talking about is supposed to trick the ECU that the EGR is closed, would disconnecting the line that goes to the exhaust do the same thing? http://fordfuelinjection.com/index.php?p=61

There are 2 smog pump hoses that go to the cat. converter? Could I just weld a cap on them at the cat?
