Why does my exhaust whistle?

Just recently noticed this whistling/tweeting sound. What is it?

Mine was doing the very same thing for about a year now. From what I can gather the internals of the muffler break (rust) down in a way that causes this. Of course mine was after warranty.

No muffler will last forever but I was hoping for a little more than 4 years. I went back to my Cherry Bomb and some mods that smoothed things out. $50 on muffler (already had one) and parts looked like a better option than a new factory pipe.

Falling down is your bodies way of saying you just screwed up.

So will it hurt anything if I keep driving this VW bug?

Nope, it will just continue to rust away over the years naturally. Who knows, it might go away after some time but I couldn't stand sounding like the Jetson's car. If I get board I might rip into mine this winter for something to do.

Same happened to mine while still under warranty. Tried to claim but feedback from Japan muffler is not in the warranty list said by the local dealer. Tried to cut it open find the loosen bit causes the sound but everything seem fine. End up replace it with an used one.

Mine has done this for a couple of years now. I think it might be in the cat. I may buy a Yosh this winter as the sound is just getting too bloody embarassing.

The catalytic converter has a honeycomb like structure that sometimes falls apart. This could plug up your muffler (it would get very hot and possible glow) and would cause strange sounds in the muffler. Here are some broken/plugged ones on youtube:
