Loud pipes don't save lives. Just think about it. You are going down the road in your car with the windows rolled up, enjoying the air conditioning and the too loud radio. You decide to pull out and pass the slow driver in front of you. There is a motorcycle in your blind spot. You won't hear his loud pipes in time to warn you not to pull out. The sound of his pipes trails behind him, but to save his life, they must speed ahead of him. Loud pipes are for the thrill of the rider and they annoy those who don't appreciate them. Also, they might be exciting for short rides around town, but after a long day of riding, they still pound in your brain and exhaust you as well as your motorcycle.
