Exhaust leak question for yall

[HeadacheManNYC]

This may be too subjective, but how does the location of an exhaust leak affect the sound it makes? Depending on where it is, will a sound necessarily present itself when a leak develops?

In case it isn't obvious I'm looking for guidance in trying to pinpoint the various noises/vibrations emanating from my 3FE.

Thanks

Leaks and their noises!

Sources of leaks and sounds:

1) Manifold to head: Makes noticeable report that sounds like a single cylinder is leaking gas under pressure (pfft, pfft, pfft)

2) Cracked manifold: Same as #1 or #3, depending on position of crack on the manifold.

3) Exhaust flange gasket or pipe through to the muffler: Makes loud growl from all cylinders (blobla,blobla, blobla)

4) After muffler, more sedate rumble, rather mellow and performance sounding.

That was fun to describe! Hope it helps!

How does that exhaust flange leak go again...?... Are there hand gestures involved in these discriptions? or just silly faces?

So of 1-3, which is the biggest pain in the ass/most expensive to fix?

All three require removal of the manifold combo.

Bust out the ibuprofen headache man,
