What's the standard muffler? Morris sells a BCM Pitts style for inverted mount and side mount. I ran one with the inverted rear Pitts style for the zdz40rv-l, all I had to do was enlarge the holes in the muffler slightly. I have an mvvs2.15gas witn inverted Pitts muffler going on a Hobby People 80" Cap232. I also have a custom header and a Macs 35cc tuned pipe for it, but can't fit it. Interested in pipe and header, which also fits OS BGX and OS1.60FX, contact me, they are both anodized red.
