Anyone figure out a solution or alternative pipe that has removed this sound?

yep, it is the aft support brackets on mine, i bought a small dia washer drilled the hole to allow bolt and used as a shim tighten up fit also had an issue with a bracket hitting mount .. had to grind it down about an 1/16 { bracket is wider than spacer,} it will stop brackets on pipe from pinching and tightening up, leaving aft support bracket to rattle at stops and so far no more rattle
