Mc Master Carr carries silicone and teflon tubing that will work fine. Suggest you drill and tap the exhaust stinger at the end for 4-40 button head screws. Put a couple 1/8" button heads on it and then slide the tube over them and secure with a tie wrap

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.
