Plus if you add downpipes its really lightning the load on the turbos. Essentially, im not surprised that set up gets better MPG:biggrin:

+1 Noticed about an additional 2 mpg, despite me flooring it more often to hear that sexy sound of the intake. If I drive conservatively might even see a little more.
