This logic is known as the slippery slope fallacy, it really doesn't hold up.Is it possible to own a gun and not use it to commit murder, rob banks, threaten others, and what else convicted criminals do with guns.
Just because there are some out there that commit crimes with guns, should we ban all guns.
I believe what the O.P is saying is that although he has loud pipes, there is no proof that he is one of the perpetrators the relevant loud pipe laws intended to target.
If they can ban loud pipes, they can easily ban sport bikes, or all guns following the same logic..
They have DB measuring tools - you'll seem at White Rock beach in the summer issuing warnings and citations. Those with pipes restore them to stock, go get them certified, and then modify them all over again.
