This is some of Holiday Park campground on West point lake near LaGrange Georgia, my bike 4-strokes some below 20 mph. The speed limit through the park is 15 mph so I tried to keep it close, I did clean it out a couple of time when not near campers.
I went riding through a campground in Tennessee with a couple buddies.... No baffles, 3 motorized bicycle, and a couple guys that might like to show off.... It was fun for us.... The people that were in 1-2million$ campers hated us lol
Mine is not that loud, but louder than stock. I'm running a modified stock muffler, no baffling and duel stingers. Its small and tucks in tight to the bike and gives 31-32 mph on flat ground on a 48cc engine. I did wait till mid morning just in case tho.
