Good on you Ken.
SS muffler: I had one custom made and fitted to my 120, 1602/1191, about 30 years ago and it still shows no sign of age.
Acid moisture from the combustion tends to make a non stainless muffler most prone to attack after short runs. My previous non SS mufflers struggled to last 5 years.
Tinny sound probably comes from thinner casing some may use, not a problem with mine, even though it should be 6" longer (their press was too short). Pipe diameters also make a big difference; 2.25" header for hot gasses, 2" or 1.75" tail for cooler gasses seem to work well, quieter too.
