I installed my Magnaflow cat back system part #15778 sometime last summer and today I notice the tailpipe is rusting. Now I thought all there components were stainless steel.The muffler looks almost the same as when I installed it but the inside and outside of the tailpipe are pretty rusty and not surface rust, I'm talking about flaking kinda rust.The clamps also look like there is some kinda plating peeling off.

I'm wondering what grade of stainless steel there using,if it's 316 or 304. Anybody have any thoughts on this before I contact Magnaflow.

My magnaflow #15818 catback appears the same, just without the flaking. I believe it's stainless, just a lower quality so there is still a small amount of corrosion.

      2020 Trailboss 6.2 replacement

      Correct.  2019-2020 are serviced by a different p/n.  19420611.   The recall engines 2021-2024 are serviced with 12740076.     What the difference is between the two, I'm not sure, but 2019-2020 only show 19420611 as the replacement engine p/n.

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
