Here are some pics(hopefully) of the second muffler I added to quiet things down. I hear more engine noise than exhaust. Brand is Nelson and model # 1N89. My dad bought these to use on some generators and ended up not using them. I had intentions of making some flanges and welding them to stock muffler and add-on to make them detachable but never got around to it.
