Default What is inside the exhaust pipe?

I have been chasing down a squeak/squeal coming from underneath the car. It happens when I let off the clutch and for a second or two after full clutch release as I am applying power. I have replaced the throw out bearing & slave cylinder, checked all the bolts. I'm down to either the clutch itself slipping or something in the pipe.

Question: is there anything inside the pipe that may be squealing? A baffle or something where the weld is coming loose and the pressure change from off-throttle to on-throttle causes it to wiggle and squeal? I'm about to pull my hair out over this noise.
