Right, I am getting around 32 KMper gallon. I forgot to convert to miles. My bad, I thought that number seemed a bit optimistic. Divide 32 by 1.6 and you get 20. Thank you sir. (you're the one on the left)

In any case, I am getting around 11.8 to 12L per 100km vs 12.9 or higher prior to putting on the exhaust. I open it up regularly ie. I don't drive more conservatively for 2 reasons. One, the drone is at its worst around 2K RPM. So, I try to get it over 2500RPM as quickly as possible. Second, the sound of the exhaust at WOT is addictive.

Bottom line, I love this exhaust.
