I have a stage 1 pfl with a cete valve controller, thinking about a secondary decat but I do like my neighbors, how much louder over stock is it in comfort mode with valves closed on start up ?
 
No difference, only really notice on boost. You can hear turbo turbine airflow more and sounds less muffled

I’m in the same boat.
Cete valve controller which is great, but a pair of OEM decat pipes waiting in the garage.
Some days i’m itching to put them on but others it just sounds so loud already that i think i can’t get away with it!
