I have a Zenoah gas engine. I have a header with a 5/8" pipe. I want to use some type system to route the exhaust to a can muffler mounted to the rear of the engine area. Can you use a piece of heater hose for this? I also have some of the flexible metal gas line hose. Can you somehow connect this material to the ends of a header and muffler without it vibrating to bits? Any advice or personal experience would be appreciated. Thanks.
