How To Make KTM Duke Exhaust Silencer Sound For Any Normal Bike

 I will help solve your problem and its very simple to do: Use a clothes pin and a playing card (My favorite is an Ace of Spades. because its cool) attach the card securely to the frame next to the wheel with clothes pin,  the other end of the card should face into the wheel and  make contact  with the spokes as they pass by.  Adjustment is key here.  Not too much contact, or the spokes will pull card away.  Not enough contact, will result in a very weak sound.  Find the balance for that perfect "Tut!" Sound.  When you find it,  your good to go.   It will sound like a real motorcycle.  Forward or Reverse.  If done right,  you will not hear that exhaust anymore,  Just that card flapping. tut, tut, tut, tut...Happy motoring.  Who out there hasn't experimented with sound levels. As kids, we would peg cigarette packets folded flat to our bicycle spokes to emulate motor bikes. HDBD Hackers, I applaud your video, thanks for sharing...  I did the can idea on my ATV when I was about 15. Take a piece of 2” or 2&1/2” exhaust pipe and hold it about 6” back from the exhaust tip. It was loud.
