Fox made a tilt up and a tilt down muffler for the .60 and .74 engines. The mufflers were the same size. In the past Fox also used to make a Fox Quiet Muffler which was a long length item that worked like a tuned muffler. The Fox Quiet Muffler also came in a tilt up and tilt down type too.
The Fox .78 used the same mufflers that the Fox Hawk .60 and Fox Eagle I engines used. These mufflers do not fit the Fox Eagle II, III or IV .60 engines or the Fox Eagle .74 engines and vice versa.
Now then the MVVS 10cc engine mufflers happen to be an almost perfect fit. You may or may not need to widen the screw holes in the MVVS mufflers ever so slightly to fit with a jeweler's screwdriver.
