Any numbers on the BMW performance exaust

Hi, I like to stay stock as much as possible and when BMW offers an upgrade, I like to take it, especially when its put out by the M division, I have the performance pack on my 135 and once again,,they lie on numbers,,,hot as hell!!! But on the exaust, they don't give any figures, the cost posted on bmw is reasonable compared to aftermarket,,yeah pretty unusual, but does anyone have,,1 a better cost and 2 numbers and specs,,ie,,,hp trqu gain,,,reduction in flow resistance etc
