[Water Warrior 2]

I have to agree with Alantf when it comes to noise levels whether they are bikes or industrial in nature. Excessive noise is destructive to each of us no matter what the source. I didn't always believe in quiet pipes on my cages but they were more of an annoyance as time went by. One loud bike was enough too.
Having permanent hearing loss from industrial sites is also part of my life. I won't go into loud music for fear of sounding like a complete idiot with the added hearing loss I created.
