Egr is for nox emmisions the hotter the combustion temps the higher the emmisions.
Egr works by recirculating a part of your exhaust gas back into the combustion chamber to be reburned and the downside to this is it mixes with oil vapour and creates sludge that can potentially jam up the egr valve itself and intake manifold
On a petrol engine I've never seen a bad intake full of carbon/sludge with egr fitted unless it's a direct injection engine.
Personally I would leave your old tech egr in place as it's not that good at recirculating exhaust gas to cause you a problem👍🏻

Hi, very old post but I’ve been looking up EGR discussions, I’ve bought a 95 P10 eGT and the pipe going into the EGR has been cut off, can’t see a blank anywhere but presume it must be. It has an after market manifold on it.

Just wanted to understand, what is the benefit of removing the EGR? I imagine it’ll impact emissions but is there a counter performance benefit that makes it worthwhile?

We've all advised on what we did etc...  None of us removed the CC, just blanked of the actual EGR pipe. No reported problemsSmile

Guys, I figured out almost everything. I wrote a How to thread in our forum but only as it is up to the EGR & BPT.
 
I still don't know should I remove the Carbon Canister or keep it. Most people advise of getting rid of it. But I don't know what should I do with the hose coming out from the fuel tank and ending in the CC. Some people say it could be plugged, other advise to keep it unplugged upright but there might be a smell of unburned gas fumes under the bonnet and the cabin..
 
Has anyone went so far - to remove the CC? If yes, please advise of how to reroute/plug the vacuum hoses. It is only a matter of some more efforts to figure that out too.
 
Thanks and regards,
Martin

all the ones I can think of have a hole for your EGR
I got it from ebay. A friend of mine advised me of it and he said it is a great one as he already installed it on his N15 GTI. Plus the seller seemed to be a very nice guy as he is.
The thing is the header don't have a hole for the EGR only for P10 eGT Confused
The pictures below are showing my SSAC with/without thermo wrap (this thermo wrap was a pain in the ***)

Maybe you are right, I should keep the carbon cannister. I will look for a way to remove it as well as it makes no sense keeping it when EGR is out. For right now, I will probably keep it

I found these on other forums. A guy removed the EGR and the BPT valve and he had two hoses to worry about. He simply tapped them Shocked He kept the carbon canister as well. I think I will try make it his way..
 
Things look a bit better at this time Confused But still I am not that confident..
