Dyno results
Has anyone ever dynoed their cars with either the Porsche or Fabspeed exhaust? I am very interested in the results.
Although Porsche does not advertise any HP gains, I thought they said that simply to avoid the red tape.
Does anyone have proof other than the sound (being different) that there is a true gain somewhere?
