Noisy exhausts are fun...for about half an hour...at the end of a few hundred miles you'll have ringing ears. Ask any tinnitus sufferer or any Harley rider over sixty years of age. They'll probably shout their reply..
I like to hear the engine note but not a constant braaaap, plus most of the British Horse Society will want to lynch you if it's too noisy!
Now, if a valve could be fitted somewhere we'd have a choice..
