Awesome results
thanks to RPi and dbae1978 for their efforts... looks like we finally have a viable exhaust option for the 535i! Just curious, the dyno sheet that was posted showed lower hp and torque at high rpm's, which I'm assuming is heat soak given the 20+ pulls that you all did... wondering, however, if the first couple of pulls showed the same increase at high rpm's that we see throughout the rest of the powerband. Thanks!

all the dyno results had similar results and very consistant. All dyno pulls are always measured from 4th gear, hence the higher rpms.
