I have an old Track Magic Demon with a TM Moto engine that hasn’t been out in a few years because the local autocross club (SSCC) decided that it didn’t like shifter karts. So if I am going to get to run at all this year it will have to be with Emerald Empire in Eugene Oregon and that is a 3 hour drive away. They have much stricter noise regulations though. The 95 db max is strictly enforced. I have the long TM moto pipe with the large muffler that runs across the rear bumper but I am unsure of the noise level in db of the big TM mufflers? I would rather be super safe rather than get booted for noise, with a 3 hour drive each way. Any feedback or suggestions?
When I ran my TM moto for part of a season, it was quieter than my Honda CR125. Using some junky silencer off the TM pipe. Repack your silencer with some fresh packing and it should be good. We had a 96 db limit and I never approached that – but did get in the 93-94 range with the Honda.
