smoke
I don't know all the details of the new law, but the one i have confirmed is no smoke, that is if it stays in its present form.
There will be an add on kit for diesel that do not pass, something like a cat converter, and if i understand it correctly once you pay the 1k for the system your diesel will pass, smoke or no smoke.
again thats the one item I have been informed about.
hopefully I am wrong, just wondering if anyone else knew anything about this.
