23 LT1 Exhaust sound “turning off”

I drive around with the #15 fuse removed so the exhaust valve stays open all the time. I’ve had my 23 Camaro LT1 since 10/2022 and didn’t have any issues until about a month ago. It seems to be happening more frequently - every time I drive it now. Before, it only did it maybe a handful of times

Whenever I’m cruising along around ~2,000rpm there is a very quick “screech” noise and the exhaust sound turns completely off. The only way I can get the exhaust to make noise is if I give it some gas, and as I give it gas it sounds like a “schwoop” noise and the exhaust sounds like it opens back up and makes noise. I noticed it doesn’t matter the speed or which gear I’m in, it’ll always do it.

Anyone have this happen? Not sure if something is wrong or if this is typical from removing the fuse. I’ve removed the fuse in my 2021 LT1 and never heard this, same with my current one up until a month ago
