Me too. I also use the ss strap method. Works great (300+ hours) and since the hangars are edge-on to the slip stream, they are low drag as well.
(still flying the spintech but have a Flowmaster brand Hushmaster II on the way. It looks more aerodynamic than the spintech but don't know if it will stay together.)

Hi Rusty;
I used some 3/4" stainless steel banding. When I built my own "SpinTech", I welded on mounting tabs at each end. I used 3/16" SS "pop" rivets to fasten the banding to the muffler and to the fuselage mounting points. It made a secure yet flexible mount (but not too flexible). After 35 hours of engine running including 17.5 hours of flight (and a few minutes of gliding :-), it still looks as it did when I installed it. I checked it 2 nights ago when I was removing some panels for other maint.
