Yes as long as the area that takes the impact of direct exhaust gases is at least
.125" thick. If not weld a patch on just that area.

I assume it is a tangential muffler. Correct?

Take some pictures and send them. Cell phone pictures are OK.

BTW don't let the oil cooler or the water radiator "see" the bare muffler.
Heat radiation is a big problem.
