Please take this in the spirit intended, but the quieter our bikes are the better it is for all of us. Most folks in town can't tell the difference between a Harley with open pipes vs. Dual Sport without an insert. They just hear a noisy moto. You should be able to look up the test info to see how you are doing. Some riders have also added a turn down on the pipe to bounce the sound off of the ground first to help dampen some of the noise. The exhaust sound from a big 4 stroke will also carry farther than a 2 smoker for example.
I am sure my SuperTrapp is not the quietest pipe option, but I keep the packing fresh and have played with the disks and found the compromise between quiet and performance I can live with. Like to know how that app works.
