The Soundmasters I have have holes drilled in the muffler flange as well as a strap for strap-on installs. I like the latter method as it allows being able to use them on multiple engines. Their sound is very nice and they are much quieter than many OEM mufflers. There is a weight penalty, but I feel it’s worth it.
