The silencer is only there to reduce noise, however one should probably tape/plug the hole left after cutting it so you don't get extra dirt flying in.

you have to put it in specific spots (where the plugs are).

I did this too except I just used old rubber mousepads. The best fix I have found so far besides taking apart the dash. You really have to jam it down there, I used a rubber spatula. It's kept the dash quiet for months now, a new record.

I see the same one all the time in the neighborhoods surrounding san jose municipal golf course. I guess he lives there.
