RE: dle 20 cc muffler extention
I tried using high temp silicon hose but the gas exhaust fumes kept eatting into the silicon and splitting it. I now use a rubber radiator hose from the auto parts store. It already had a couple of 45 degree bends in it and is a snug firt on the end of the stinger with a plastic tie for good measure. I am running a DLE20 with the noisey stock canister muffler, but the hose extension has quietened it down alot.
