He’s obviously not a Harley rider, but that’s okay. It’s not for everyone. No amount of argument will make a non Harley rider love them. You either get it, or you don’t. I would disagree with him on two points. One, speed does not make a bike safer. Most single vehicle accidents (motorcycle accidents) are due to excessive speed. Two, loud pipes most assuredly save lives. Personally, in the first 500 miles on my Harley I had three incidents of people coming out in front of me. I put moderately loud slip on mufflers on, and in the subsequent 7000 miles not one incident. So in my experience, loud pipes get attention. Sorry if that offends people, I’ll put the stock mufflers back on just as soon as drivers start paying attention and stop trying to kill us.
Physics disagrees with you about loud pipes saving lives.
