I’ve searched this forum and couldn’t find anyone who’s tried this muffler delete kit on a 6.2 w/ DFM. There’s lots of talk about flappers and removing one, both or none to address the sounds made by DFM. Has anyone just followed the instructions below, and if so what was the result? Any good?

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
