What is wrong with Honda's exhausts

[LongRanger_imp]

And in California as of Jan 1 2013 it is illegal to modify the exhaust on any motorcycle manufactured on or after that date, CARB compliant or not.

Not enforced at all.
Looks like the 2017 did a better job on slimming the can down. I stand by what I said the stock can it is way too heavy, Quiet and Large.

That's too bad. We have the same laws in this state, and they're ignored too. Law enforcement probably has better things to do with its time, so the scofflaws are able to persist unimpeded. I see it with texting drivers all the time.
