You can call out hooliganism or whatever the bad behavior is without making ridiculous claims about how engine noise is somehow illegal. That not only detracts from the point, it makes the poster look sort of ridiculous.
There are legal standards for both vehicle noise and vehicle emissions, at least in the UK. When owners modify their exhaust to make them noisier, they are likely breaching one or both standards. It is specifically illegal.
