Some people complain about the drone from some exhaust systems. Borla is popular system. If I went with a exhaust system it is what I would go with.

Lady at the parts place at the dealership mentioned some valve in the exhaust system thats new in the 16s and was not there before. Never heard of it til she mentioned it and it made me back out from installing one.

The valve was on my 2015 it's not new

If you're going to get an exhaust system get a tuner to turn off AFM

Borla system is like 800-900

My Dynomax was 374, it's stainless and I bought the Diablo intune I2 for 350.

More mods and still less money spent FTW

So a tune is mandatory? And the exhaust system youre talking about is a full exhaust system from heads to tip? Or just cats to tips?

The 14's and 15's all have the valve and it's to prevent drone when it drops into V4 mode. The GM Borla exhaust comes with a valve to eliminate the drone and is the only one that comes that way. You do NOT need a tune if you have the valve and your AFM is on. If you use another exhaust just have the muffler shop cut it off the and install it in the new exhaust. The GM Borla is a Cat back system and you can do it yourself.

Cool to see another 2016 high country owner from Texas. I usually install cat back systems on my trucks but I'm gonna skip it on this truck. No tune is necessary for an exhaust install. Unless you wanna void your warranty don't install a tune.

AFM = Advanced Fuel Management and this is what changed your engine from V8 to V4 mode. If it did not go into V4 mode there would be no need for the valve in the exhaust. The guys that have tuned their trucks don't need it because they turn the AFM off so it's always in V8 mode.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      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

      By GN2018 · Posted

      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.
