I have the 817746 Flowmaster set-up on my 2018 2ss with the fuse pulled and the K&N Blackhawk cold air intake. It's very loud on start-up because the Tach starts at 1200 rpms or so to warm-up, but once the Tach drops to 500 - 600 (idle when warm), it does not sound that loud.
As for WOT, it's hard to tell because the exhaust is in the back.
I'd call Flowmaster. I'm sure the engineers have that decibel number.
