I did the Jesse style exhaust mod on mine and it does increase noise levels but not enough to be even close to the 94 db cut-off level. I would say that while it make the bike noisier it also makes a change in tone, deeper I would say. When compared to my brother in law's stock KTM 450 it is much quieter even with the mod.
