Just ran against a 2013 M5 stock against my 2013 550xi with Dinan stage 2 and it was even to 100mph. From a light I power braked to 2500 rpm then punched it, I was instantly ahead by 1/3 car length and then he caught up around 60mph and was clearly going to pull ahead if we had gone to 150. We had to stop due to traffic ahead. I have to say I was really surprised and so was the driver of the M5. We had a chance to talk at the next light and he couldn't get over that he couldn't hear my car. The stock 550 exhaust is so quiet.
