My muffler from RC Specialties came and I am installing it. I also ordered a new bendy pipe on back-order but will cancel that.
The cowl may have to be modified a little to work with the new muffler but not too much. The pix is from their website.
The other issues for the repair are the landing gear which was bent pretty bad and the cowl with some local damage on the bottom front. It will be glued back, reinforced with some fiberglass, patched up with bondo and repainted.
