  1. Do you have the bulletin number?
  2. I wonder if someone could do a polyurethane boot.
  3. I can confirm it's not the cats. I'm Long Tube headers to aftermarket cat back. Entire stock exhaust removed and it's still there.
  4. I have long tube headers and an aftermarket cat back. It's still there.
  5. That's more or less what I meant. Overall cost of all the units needing repair.
  6. I think GM doesn't want to get involved as I'm guessing they know the cause. I'd imagine the fix is probably expensive.
  7. Only other thing I can think of is something in the valve train. Mine got louder after long tubes.
  8. Fuel or transmission is the best I can figure
  9. I've got long tube headers and an aftermarket cat back. Ball flange was replaced with a V band. Noise is still there
  10. Slight movement of the engine. I can't think of anything else.
  11. Did they give you a bulletin number?
  12. Did not go away with the installation of long tube headers and header back exhaust
