Have had my dbs for 6 months now, and was curious to know that whip like start up exhaust note occurs at times and at times not. Is that normal or should it produce that aggresive tone every time? Thanks guys

 

Mine occurs when the car is really cold.. I'm talking about the aggressive whip sound.. but when I start it after parking it for a short period, it doesn't happen.. so I say as long as there is nothing really out of the ordinary, like you need to hold the ECU in longer or something like that, I think you are good..

enjoy the car in good health
