Well I broke the motor in today. Despite Hooking up in a chain 3 pipes (standard .12 pipes) to a sx15 ev5 the noise still was insane. They were simply copled together using zip ties from inlet to outlet.I haven't had the chance to fab my above mentioned design, but it makes me wonder if it will be worth it. It didn't seem to make a difference. I put some ear plugs on but I managed not to tick off any neighbors.
