True, forgot that dyno was over Dinan.
At any rate, I am interested to see what such a ludicrously expensive (I understand the asking price, just could never personally justify it) set of headers does to the M62b46. With tune, I still think it will be closer to the 20-30whp range over stock. Still very interested though. I'd be excited if in your shoes.
