BMW headers are great stock....particularly since they are hydroformed.
I know that you don't get too much. But 0.4 secsonds in the 1/4 mile is a good number IMO since the car already has a good time in the 1/4 mile to begin with. We both know from following the M5/M6 board is that the aftermarket headers do indeed provide about 35-40hp. That's all I was trying to say.
