 DB volume
 At 5500 RPM, all options are below 97 dB (tested with exhaust flap in closed position) For higher DB values, you will need to remove the cables from your exhaust flap valve to open the flap. This enables much higher DB levels (max. 104DB). When the flap valve is open, reassignment is still not necessary. (Race Use only!)
