Hi, my mistake , Brembo not Baer brakes was what I meant. Was the difference in power obvious after the fix of the SC, night and day? Sounds like you got a great deal, I think if you research the idea of a different exhaust it would greatly increase the power. Keeping the tips would make it under the radar and new exhaust would take advantage of the SC. I kinda of envy you because the X5 is very nice with all the goodies it came with, again great job on the detailing.
