You are better off to keep it.
People get rid of it because it puts exhaust in the engine, and carbon in the intake.
However it lowers combustion temps. This means you keep power with a load on the engine, and do not have to worry about predetonation as much.
Same idea for the pcv valve. People don't like them, but oil/fuel vapors in the intake. Adds to the mess that builds up in the intake.
However without them. (used to be a tube off the side of the engine. Oil had to be changed much sooner due to sludge buildup from a lack of air flow to pull the vapors out of the crankcase at idle.
As much as people do not like a lot of emissions both of those are one's you are better off keeping.

Keep it... I deleted mine and wish I would have kept it with my new headers. EGRs allow more ignition timing while cruising for more power and fuel economy.
But if you want to know. On the drivers side header there is a pipe that routes from the rear of the manifold up and runs along valve cover into the intake manifold. 1 or 2 bolts on exhaust manifold to remove, and the pipe is threaded into intake manifold (don't remember what size wrench i used but it was decent sized. Take upper radiator hose off for better access. Once removed you need to plug both manifolds with egr delete plugs or equivalant sized and threaded bolts. And last but def not least you would need to have the EGR tuned out to prevent codes being thrown etc.

Do not delete it. You will do more harm then good.

I have also considered this and come to the conclusion that it would be better to keep the EGR on but I am wondering if there is a way to filter the exhaust gas before it spits all that carbon into my intake, maybe a metal filter that I can re-use, something I can clean around oil change time? Is there anything like that out there?

If you are getting a lot of carbon build-up, then I would be looking elsewhere as to why as opposed to just trying to filter it. And to my knowledge I know of no such device unless you want to make one.

just keep yoru engine runnin clean and smooth to prevent excess carbon. maintenance and tuneups.
Excessive carbon buildup is a direct result of excessive oil in the cylinders being burnt.
This is from Blow by, due to leaky ring seal and or leaky valve seals. but more commonly is rings.
Leaky valve seals will cause a short puff of blueish smoke from the tail pipe immediately after start up, but still contribute to the carbon build up problem.
Blow-by increases crank case pressure which in turn forces the atomized oil that's mixed with crank case gasses to enter the intake Via PCV valve.
The best method to fight this without re-ringing the pistons.
Is to install a Good (not a cheap pos ebay) Catch can and Clean the intake out.
By removing it and spraying it out with a de-greaser, (berrymans B-12).
This will ensure a immediate reduction in oil being burnt and the creation of more carbon buildup.
Creating a nice clean and happy engine.
