I can't get the idea of a muffler below the engine with side dumps out of my head.
What are your thoughts on primary length, dumping into a volume from either side and exhausting on both sides?
Rough image of what I had in mind (SV650 engine... Rough..)
What would happen if you skip the muffler all together and dump straight down from the primary?
What sort of diminished performance might you expect if you dump into a muffler like the image? Does cyl 1 and 2 help each other? I haven't found anything online, but remember seeing that on car shows. Equal lengths are important..etc.
