How much is the Gruppe M exhaust? Intake looks great, but I highly doubt that successive dynos would show the 7-18hp increase discussed earlier. I am thinking this increase is likely due to the filter in the GruppeM unit being less restrictive and not the design on the intake. Wait a few months, drop in a BMC or Streamline filter when it comes available, and I bet it would show the same increase as this intake for $2500 less. Very pretty intake, but for $2800 I will pass and much rather spend that money on an exhaust...
