Default Troy built models muffler silencer?

Just ordered a dle 30 from them(excellent deal) and it includes a ngk plug, drill jig and something called a muffler silencer. Basically it's a baffle that plugs into the exhaust tube to help quiet it down. Anyone use these yet?

I installed one on a DLE 30 with the stock muffler and I couldn't really notice a big difference . I don't have access to db meter to measure the levels . Maybe someone with a meter can give us some numbers .

I have the smaller one which i run on my NGH 17cc.

It definitely takes the harshness out of the exhaust note and gives it a more bass'y tone. I don't know if it reduces the overall dB level by much at all, bit it's certainly more pleasurable when standing close to the engine.

Loosely fill some coarse steel wool in your muffler rather than plugging the outlet stinger. It attenuates noise more efffiently with no real loss in power unless you cram it full. Another more effective silencing tip, install some soft silicone rubber to the stinger, about 8" long

Are they any concerns about the steel wool breaking down and getting pulled into the motor?
