I am set up in Pittsburgh, PA to do media blasting and Noise Maker deletion on R56 MCS models as a side gig. $250 a shot, includes new head to intake plenum gaskets. I am also in the process of piecing up a low cost freer flowing noise maker delete solution as well. I have been turning wrenches for 20+ years and am a mechanical engineer that minored in automotive systems design and dynamics at a Big 10 college. shoot me a PM if interested.
