you will be fine with the SS muffler and any of those props (except the 9.25 pitch as noted)
in fact, if you want something scarey, get the 8.5x7.25 prop
A little magic occurs.
Say what? For which motor? Seems light for the SJ50/SS combo. Looks like the right load factor for the .50V1 though. Whatchoo talkin' about this magic? Don't tease me like that!
