Road Trip Through California? Emission Regulations
 

So have question for Anyone that may have an idea of the answerer.

I live in BC, Canada and have an 07.5 LMM 2500 Gmc with the all Exhaust filters and crap removed and was thinking of Doing Road trip sometime in the near future down the west coast through California.

Wanted to know if i would have any issues going through there with an unfiltered diesel, a buddy was telling me a story of a guy that went down there and a cop forced him to be towed all the way back to the boarder. Just wondering if that's true.

Couldn't find anything on the interweb about "The land of fruits and nuts" :tttt:
