Best FMF silencer for spark arrestor

[seanmx57]

Which one is the "good" one. seems they have had several models over the last 20 years.

I've got one that looks a standard silencer, it's short, says ISDE on it, no funky shaped can on the back like the Q. I've got a turbine core 2 and a Q as well to pick from.

LMK if you dont end up using the Q or the Turbine Core2. I need one as well...
