All Input is Greatly appreciated!!
I have a 2000 Maxima se, and the only work I have done so far has been to the look of my car. Body kit, aftermarket lighting. dash kit, et....and an aftermarket audio system (the factory bose system sucks balls!). But I was wondering what is the first thing I should do to increase hp, mpg, and overall quickness? I was considering a cold-air intake, catback exhaust system, performance chip, but I have to do one thing at a time.....any suggestions on the steps I should take to make this a quicker, more efficient car?
