If you get alot of situations where you are unable to let the process finish you will have to deal with the dpf getting plugged up & your truck not running properly. I have no experience with the 6.0 but I do know without the dpf system on those trucks it is 1 less thing to worry about if you can't really do anything with the exhaust system anyways. Do people get pulled over by police for this stuff down there or is it that you just have to take it in yearly?
I'm not sure, to be honest. I have done a bunch of research on here, and I was finding some threads about people with dpf delete being pulled over and given big fines even out of the communist state of California. I read one thread about a guy in Washington, whose brother got a $2500 fine after getting pulled over and checked.
So, it sounds like, since it's a federal regulation, that it's being cracked down on everywhere, or at least the chances of getting busted for having it removed are increasing.
I am fairly certain that the CA smog test guys would be very knowledgeable about what is supposed to be installed, and would spot it instantly on our smog checks. (every other year)
Thanks for the responses, guys.
