Exhaust probably isn't doing anything but synthetic oil and a more efficient air intake system will more than likely increase mpg slightly.

I got an altima coupe 3.5 and there is a hose connected to the bottom of my air box by a clip. The other end of the hose is connected to the cvt while the other end is not plugged into anything. Is the hose suppose to be connected some where or is it just a breather hose?
