That's exactly what I heard. Nice description! Sounded like my Daddy's old (early 80's or late 70's) F-250 that you had to keep pumping gas to so it wouldn't cut off. That's not what a Mustang should sound like. I wondered if people outside could hear it. It was embarrassing.

Yeah, that "tick" is an exhaust leak.

I'll let you know what it sounds like when she is welded up. Im pretty sure all you will hear is bellowing from the tailpipes after that!
