I was wondering if any 599gtb owner on this site as been doing some novitec modification... I am interested with the motor modification and the exaust modication..... People told me that the novitec exaust system is just crazy , it make a great sound.....however talking about the the motor modification ...who gives the 599gtb 808hp , well ..review are not "that great"......but i imagine that with that kind of of HP ...it must be Veyron fast..... Does anyone have experience novitec work on a 599gtb? If yes are you happy with it? thanks... Ps: sorry for english , that's not my native language....
