Odd Exhaust Sound

2024 GMC sierra Denali Ultimate 6.2 with 6k mile makes an odd exhaust sound during deceleration as soon as it drops under 1000 rpm. It’s defiant more pronounced in sport mode when the exhaust is more aggressive. I tossed the go pro under the truck to investigate. It sounds like a strange burble or stutter in the combustion process. If I had to guess it happens as soon as the torque converter clutch unlocks after RPMs drop. Was curious if anyone else has noticed this.
