Nope, no choking.  As mentioned, there is a little drone when cruising at certain speeds but not enough to bother me.  It could have something to do with the 10 speed, as the 5.3 and 6.2 are the same engine essentially just the 6.2 has a larger stroke and larger piston bore.  It could also be the resonators that might be choking out your higher flowing magnaflow muffler.

The only difference between the 5.3 and 6.2 is bore , cylinder heads, camshaft etc. the stroke is the same.

Any AFM or DSF engine is going to sound like shit with aftermarket exhaust that does not retain the valves when it goes out of V8 mode. The only options are as follows

1. GM/ Borla exhaust or other that retains valves
2. Tune out DSF ( not available yet)
3. Range device or similar ( not avail)
4. Alter your driving habits to keep the factory tuning from dropping cylinders ( annoying)


A cutout before the mufflers and valves will be effected if the truck drops cylinders.

Thanks for the correction on the engine part!  Honestly though the cutout I have sounds excellent, throaty,  and aggressive at all speeds, idling, and no matter what cylinder mode my truck switches to.

I’m thinking about putting the gm performance exhaust on my new at4 6.2 L
Was wondering how loud it is
And how difficult the install will be
Thanks for any input

The interesting thing is that you weren't able to build a Silverado with a 6.2 and this option. They only allow you to add it to the 5.3. You can add it to a Sierra with a 6.2. Strange.

There was a couple youtube videos of the media event for the Sierra.  Thsi one is an At4 6.2 with the GM performance exhaust It sounds about as loud as a Borla or Corsa touring exhaust.  My Corsa Sport on my 2014 6.2 is louder than this truck

Looking forward to hearing your thoughts on this.  I am very close to ordering.  Stock is way too quiet.

The GM exhaust uses different mufflers and piping diameter between the 5.3 and 6.2 not just a transition. The 19+ version is made by Borla but with no branding on it.

Just a heads up. The GM CAI includes a voucher for it but you need to have it programmed by the dealer for the new MAF curve. It is not a no tune intake.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.

      Another 6.2L engine failure!

      By Chevy Man for Life · Posted

      185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
