modify a stock exhaust

I was busy refuting the loud pipes save lives thing. By even making such a silly statement, you imply belief that loud pipes are somehow contributing to your safety. I think you will find I am far from stupid and probably have more experience riding on the street than you will ever acquire. I passed the million mile lifetime mark about 12 years ago.

Sound does, indeed, travel forward but when directed backward, the majority of it will go that way. What you hear when sitting on your bike comes mostly from sound reflected off the pavement and not much travels forward to reach the ears of a car driver. That is particularly true here in the civilized world where most vehicles on the road are running with their windows closed and climate control systems on, not to mention stereo system, cell phone, screaming kids and other distractions.

Assuming the car driver even does hear you coming, you are giving far to much credit to think that one will be able to determine your position and closing rate from sound alone (ever wonder why your ears are shaped like cups to catch noise from the front?). Then you further have to hope that the car driver will react to the sound of you approaching in a positive way. One would hope, do nothing, but I have seen quite a few folks, when startled by the sound of a loud motorcycle in their proximity, swerve and not necessarily away from the bike (see earlier about detecting direction of sound).

There is even some argument that headlights can act to our detriment. Many drivers use the change of apparant spacing between headlights to judge the speed of approaching vehicles and we, with single front lights present them with no useful information other than a slight increase in conspicuity. The number of accidents that include both a driver turning in front of an approaching motorcyclist and followed by the "I didn't see him" pretty much says that you could ride down the road with a flaming rocket stuck up your ass and drivers are still as likely to turn in front of you as not. A motorcycle is not seen by many drivers as much of a physical threat to them and they thus tend to ignore our very presence.

:::::you imply belief that loud pipes are somehow contributing to your safety::::

yes i am and it does, it pays to be seen and heard, it is not a substitute for safe riding and no-one implied that, I currently ride in Thailand, trust me when I say "every little helps" I often pump my horn to let people know I am there (stock pipes)

according to your statement, maybe we should turn lights off and be as quiet as possible......what ???

perhaps there may be some truth in what you say while driving at night when both cars and bikes can only be seen as a light or lights, caution is always best, when a driver looks toward oncoming traffic and sees a mass of headlights, it is very difficult to pick out the bike at the front which could be considerably closer.

Adjust your driving to the conditions, darkness - rain - fog etc.

Being heard is a good thing for driving around town, especially in Thailand, it's of little or no use when on motorways or major roads.
