What is inside the exhaust pipe?

This is a way stupid question and not intended to insult you at all, but have you checked the belts and the alternator pulley? Sorry, just trying to think of things that squeal...

You should use a mechanic's stethoscope, like mine below, to narrow down your noise search. It really does make a big difference and sometimes it'll surprise you. Uhhh, don't try using a real stethoscope.

Yep, thanks. Checked and the belt and pulley are tight.

Not a ceramic clutch, I think. McLeod single disk.

I have one of those. I'm not sure how to use it since the car only makes the sound when driving. I guess I can hang out the door with my head around the pipe and under the car, then gun it....

Years ago I cut apart a Unique muffler and this is what I found.
