Dave, You may have misunderstood something. I am using the can muffles from KS, not the tuned mufflers that look like softball bats, as I call them. Mine are short and fat with a rear exhaust. If I came across as them being a tuned muffler, I may be at fault in my description. That is why I attached some pics.
I do appreciate all the help I can get to understand this setup, cause I do like the less noise thing. Just looking to have enough power for 3D'n also.
