I've been a very good boy this year and have decided to buy myself a new Akrapovic pipe for christmas. I know that it wont make a huge difference in power, but I wonder how much louder it will be. I know that the add says 94db and while I'll think it will sound cool I dont know how many neigbors will think the same. So my question is how many db is the stock(2002 EXC520)pipe.
