DB levels tested at 5500 rpm are below 97 db on all options (tested with exhaust flapper valve as stock in the closed position)
For higher db levels you must remove the cables from your exhaust flapper valve to open the valve. This will allow much higher db levels (tunable 102 to over 110). Re mapping still not required with flapper valve open.
Please note adding any ceramic coating option to pipework adds 1 additional week to the production lead time
