Spring is here, and along with it comes birds singing, bees buzzing, and (at least around here) motorcycles thwaaARRPPpping as they drive by.

I don’t mean the existence of motorcycles. Some are quite remarkable machines. Gorgeous to look at, fun to ride.

I’m talking about those custom pipes, usually on a Harley Davidson, that someone adds to their bike. Deafening loud and distracting.

Do you know what their intended function is? Do they serve a purpose I am missing?

Please enlighten me.
