Loud Pipe design logic
"IF" loud pipes really are a safety upgrade (which they are NOT), then the loud-pipers should apply sound phyics (ha, pun there) and face the exhaust outlets FORWARD on the bike.
Then I think they could be legit in arguing that loud pipes are a safety benefit. The noise would then be projected forward. Since sound travels at about 700 mph think of the awareness gained that way! Plus, the rider could revel in their own obnoxious noise even more!
Of course, bugs, road grit, leaves, water, all sorts of crap getting air-rammed into the exhaust would be detrimental to their cause. Not to mention the fact that it would look dumb-ass stupid on any bike.
