Strange Sputtering Sound 2023 Z preformance

[ohmyfairladyz]

So a strange sputtering has started happening as the car is coming down in the rev range almost like a burble or misfire. I notice it more when in neutral rolling to a stop. I have only installed a CAT back exhaust I cant find anything definitive on line so I figured lets see what yall think and if any of you have experienced this. I will try and get video of the sound when I can, hoping it is something simple.

It's your exhaust. My Motordyne Shockwave exhaust makes fluttering pops on deceleration/downshifting. Since I replaced the cats with Kinnetix High Flows, they occur more frequently and sound deeper.

That sounds totally normal with your modified exhaust.
