The real question for most folks isn't how much emissions are impacted by removing various emissions devices, but can I live with the car post deletes.
There are trade offs of removing various components.
Example, remove the DOC and DPF means you will have significant diesel stink and black smoke unde certain condisitons and more noise. There is a long thread about this on e90post where folks have to keep their windows shut because of the diesel fumes.... might consider adding a doc,
Removing the scr catalyst, and def system adds more noise again, you'll really hear the turbo spool. But nearly no additional fumes. So from a living with it it's minor
So yes your car will be noisier, smellier, and more reliable. I would also keep in mind that under most conditions deleting the dpf and scr is only worth maybe 10-15hp, but is necessary if you want Hybrid. Removing the egr is pretty painless, it results in more orderless nox, bt improves fuel economy and reduces cbu
Also the more deleted the car is the harder it will be to sell, some folks want a deleted car but they are rare. Most won't want a modified car, as they think,it was raced and beat on. So as with all mods at best it won't help resale, at worst it hurts resale and you loose the cost of the mods and tune.
The car without emissions control will emit significant more hydrocarbons, particulates, NOx and noise. I'd suspect that NOx will be in the 40x range worse like on cheaty vws. Noise some more db, particulates is the really bad one as they are carcinogenic and you will be exposed to them. I personally wouldn't worry much, it's more about the resale, noise and stink (just use a dp with a doc)
