I'm not really sure how smart it is to start off a new truck (with a Duramax) by removing the EGR, the DEF system, the cats, and often even the muffler, but I'd like to hear about it.
I presume the warranty we paid a lot of money for would be completely thrown out when we do that, and
I'm guessing that our trucks will actually pollute a lot more without those items. Do we really not care about the air we breathe? I know that Los Angeles has MUCH cleaner air than 20 years ago, almost totally due to fewer emissions from motor vehicles.
How do we pass inspection and renew our registration after this surgery?
Does the truck show its check engine light forever, or are there tuners, etc, that legitimize the issue?
How much better will the LML run, perform, and drink diesel, if at all?
