Default Solve my noise

Sounds kind of like a car with a hole in the exhaust, has a slight smell like burning brake.
Started only on excel but, now is all the time. I've dun some google and can't find anything.
Thanks

Loose header at the head, and your fiber gasket is what you are smelling.

The make and model of the car may help narrow it down.

Thanks, that's kind of what I thought.
Sorry about the "lame description", I made the sound but, I guess you couldn't hear it...

Well, it does sound like about a half dollar size hole in the muffler of a 67 Fairlane.

There have been cases of loose spark plugs and compression release solenoids. If you had an exhaust leak from there it would make some noise for sure.
