2023 SIERRA1500 AT4 LOUD GM EXHAUST FROM THE FACTORY

Here is a outside video of my 2023 gmc sierra1500 at4 recording the GM performance exhaust sound and trying to see if I can detect when this truck is cutting down cylinders or engaging the GM DFM DFM is an engine feature that shuts down some of the cylinders to improve efficiency when the full engine power is not needed.

The exhaust sounds awesome

[@Tony-Witt]

Sounds really nice 👍

I agree, I wish the ride was little smoother, the ram rode a lot nicer .

[@Tony-Witt]

@@Garage28_28 Maybe it rides a little rough because its an AT4, and those tires also are more aggressive. Mt LTZ rides about the same or almost better than my 2020 Ram did. Sure love the power of the 6.2 along with the 10 speed.

@@Tony-Witt I think is mostly the tires , and yes I love the 6.2, I just did my 1st oil change at 500 miles I don’t know if you see the video, but I will keep this truck for a minute, I will take care the best I know how, i hope you enjoy your truck as much as I do mine… cheers my friend!! I hope you have a great week.

Gas mileage/fuel tank range/price for fill up!

[@christopherkassner8894]

0 to 60 and miles per gallon around town driving. I’m curious to see what kind of gas mileage it gets.

[@Garage28_28]

I will defiantly do mpg test, but so far docent look like she is getting good milage, she is a trusty girl, and she love to drink premium.
