New Exhaust...Improved fuel economy?
Hey Guys,
Recently had an Eisenmann Race exhaust installed. Sounds fantastic. Couldn't be happier.
Weird thing though, the fuel mileage is at 11.8L/100 km (or 31.8 mpg). Previously, I was getting numbers in the 12.2 to 12.9 L/100km (or 30.7 to 29.1 mpg). Is it possible that the engine is running more efficiently with the freer flowing exhaust?
Thanks
DC
