hey guys & gals I have a 2012 BMW 550i M Sport completely Bone Stock To the Filter it has just clicked 19k miles I took it to the Quarter mile a couple times and have ran a Consistent 12'90 and 12'80 but the best time I have had was 12'70 keep in mind my car is home stock to the filter no exhaust no tune no tire yet is that pretty fast for being what it is? I thought it was but not to sure pretty new to the N63s
