Most of us locally use silicon to stabilize the Tower muffler.
The GMS 76 muffler at $16.99 is a direct fit and quite a bit quieter. I've flown it and it works quite well but does cut a little power.

That looks NOTHING like the muffler that came with my GMS .76.
That looks more like an O.S. muffler.
Here's a pic of what I got.
Notice the double lock nuts at the end.
