Makes sense, but from what i understand, many vehicles over X weight are not included under many of the clear air acts and 3/4 ton trucks seem to fall under this category, so whilst not legal to run without the emissions devices, nothing is checked thereafter, which seems to be a large reason why they do it. Then of course you have areas out of town that aren't included in being checked anyway.
To my knowledge, these trucks don't typically have the ability to do a rolling burnout all things considered, and to roll coal only requires acceleration loading so the injectors push through more fuel than currently burnable, but it doesn't mean it didn't happen in this case, 16 year olds are notoriously short sighted in their actions.
