Default Re: how to make an engine quieter/stealth

I copied from a friend Kip Harley in Maine and cut my black muffler about 2" from the curve out of the engine and attached the two ends together with a 7/8" ID plumbing 3/4" flexible water connection. It works well to keep the output law and back out of the way pointing down to the ground. It is a lot quieter. Kip also sells kits to put sound reducing layers under the 3 removable covers on the China engines to help dampen the sound. He also with Pirate Cycles sells a quieter spring chain tightener that reduces noise. I also wear ear muffs and I am like hear no evil no more. Kip can be reached at
