Re: I find the Tanak PF-4000 ear shattering loud !
I have an HS 49CC 4 cycle. I used the stock exhaust with a modification to fit the frame. It's quiet
enough that I can carry on a normal conversation while seated on the bike with the engine running.
I do early morning breakfast runs on Sundays and need a bike steathly enough that my wife doesn't know that I heading off to eat artery clogging bacon and eggs....
I also think a quiet bike draws less attention from the local police.
