Tatone Peacepipe mufflers seem to work. I've found that the sizes are overstated. 09-19 is best for 09/10 sized motors, using one on an Enya .09-III TV. Use a 29-40 on my .19-VI TV. Have acquired a few 45-65, which would work for the .29's up. Only thing is they are a little heavy versus say a tongue muffler, but they do muffle well with adequate chamber size if one doesn't follow their stated sizes.
Also got a Tatone EM-4 Calumet on an Enya .09-III CL/FF engine. Says for 09-19, but I'd never put it on a .19. Also, I "Dremeled" out all the internal baffles to make it freer flowing. Otherwise it's too restrictive. Hear that many a modeler ruined their engines by using this muffler. As restrictive as the internal baffles are with its very small chamber size, I can see why. I drilled a bunch of holes in one and "Dremeled" out all baffles, trying to make it into a tongue muffler for a McCoy .19 Red Head. Then it lost all its muffling capability, plus it is heavy. I might patch the holes with JB Weld and use it for my Enya .15-III TV.
