That's weird! Ugh...

This was an issue on my 2019 trail boss LT. Right side was not secure and I had to snap it together on a regular basis. My new 2020 AT4 is rocksolid.

No. It’s not fixed.

Here’s mine after dealer did the update.

I grew impatient and took my truck to the dealership for the update. It seems to have updated successfully and now I have the latest version too!

How is the drone?

What version did it update to?

Do they just literally snap on over the existing knobs, or is there construction involved with putting these on?!

LT5

I think this one, but I’m not sure! https://www.borla.com/products/cratemuffler-400843

I have discovered that Borla has crate mufflers for the 5.3. I’m wondering for my ‘20 AT4 with the 5.3 if I can just swap out the muffler only and have a pleasant result? Will I lose any low-end torque, or will there be loud drone in the cabin? The muffler is about $270 which is much cheaper than the complete Borla exhaust system! Thoughts?

Here’s mine.

My ‘19 TB LT 8 speed bucked pretty good. My ‘20 AT4 8 speed is smooth as butter! Huge difference.

GMC AT4!

I owned a ‘19 TB LT and it was very loud. I mostly attributed that to the tire noise. I upgraded to a ‘20 AT4 and the difference is night and day. My GMC is way quieter! Amazing difference.
