My muffler noise just became more annoying so I searched for a TSB and found this. Thank you! When I take it in I am going to ask for a different setup. Is the GMPP any good? I think that might be an easy sell for them since it's a GM part and would be under their warranty. I was going to delay the exhaust, but since mine needs to be replaced I might as well have them pay for an upgrade for my troubles, right?
