    • Precision Sport Installs X6 M S63 Twin Turbo V8 Supersprint Downpipes

      The guys are Precision Sport recently did an install of Supersprint downpipes on the BMW X6 M. The pictures of the install show some great details of the motor and turbos. No word on the gains as there was no dyno, the downpipes retail for about $2500.

I think I saw a dyno graph somewhere of this motor with a tune, if you thought the N54 lost steam up top; this thing is a stump puller.
        This thing needs to be a stump pulled since they have it pushing 5300 pounds of nonsense.

        It has less room to play with from tune alone, definitely, as it is a higher state of tune to begin with.
