hi mick29 here, is it posible to quieten a standard exhaust that comes with the 50cc motorized bike kit, if you remove the bottom cap and fit steel wool in the muffler part, replace the bottom cap will this restrict the exhaust flow too much or is there a better way, im trying to make the bike quieter because round my way everyone seems to dislike motorized bicycles, dont know why, i think their great fun, theirs problely been one or two people that have spoilt it for ME. Any ideas would be really great. Remember ride safe everyone
