thats sounds pretty chill, but wouldn't getting larger piping like 3" allow for better air flow, after this exhaust gets put on a CAI is going on Steeda looks like the best bet I've been calling K&N though cuz ive used their products forever and they work great for all my other toys, but the big thing I want to do to the fusion is to put this new super/turbocharger combination I read in a magazine think it was called a centrifugal turbo something like that it pretty much was the super charger pully system attached to a turbo. This is just a fun project car.
