Didn't know RPI had a exhaust system available for the F10 M5
I'm sure it makes power however to say it provides the most horsepower of the three is pretty bold ...
I would love to see all 4 exhaust systems installed on a stock F10 M5 and see what kind of power each system makes.
(Pretty sure everybody on this forum wants to see that too)
