So I was recently at Stonyford, CA riding when a ranger stoped by my camp to "educate" me on some new noise pollution laws. He said that he wanted to test my bike to let me know what decibal it is at for educational porposes. To make a long story short my 01 426 spit out 113db with a Pro Circut T4 exaust. He said that I was so grossly over that he should write me a ticket anyway. He let me go and said "don't come back until you have new exaust". I am fine with all of this, I don't like loud exaust anyway. I recently read a Dirt Rider mag that did a comparo on exaust systems (with db ratings) and the spec they gave for the T4 was like 103 (or something way off of what my bike was tested at). I am thinking that they did their test at a different RPM or something. So my question is, I am ready to go any buy something more quiet so what do you guys run and how loud is it? Thanks for your input.
