My buddy Mike68 has been telling me about his work with the treehuggers in NH and I've been following the threads about noise. On this site and others. It is a huge and sometimes heated topic. But now, I think I need to consider my impact in decibels. I run a White Bros pipe and 12 discs. It's loud, very loud. I do love it very much and love not having to loosen the header to change the filter. I have also gotten close to jetting perfection , but now I feel guilty. I only ride in ATV parks or MX tracks. I won't put the stock exhaust back on. I will consider removing some discs and rejetting Especially considering may ride some public land this summer. Thanks for making me consider this "for the long haul". Bill ------------------ 86TT225, 99WR, WR timing, throttle stop trimmed, air box lid removed, White Bros head pipe, silencer and air filter.
