So you thought my rattling/ticking noise was an exhaust leak?

Did someone put some nuts in your hubcabs?
That's what I thought, but then noticed that the sequence was - rev, wheel starts to turn, let off gas pedal, ticking starts...guess that could be centrifugal force in the wheel easing up, allowing the nut in the hubcap to fall away from being pinned to the hubcap...but seems like it would go rev, tick tick tick, quiet, release pedal, quiet, easing into tick tick tick if it were a nut...
