Shorty headers will match up to your y pipe so you don't have to change anything and they will give you a little more horsepower over stock manifolds whereas long headers give you more power over shorter Headers but you will have to do a lot of pipe bending and forming to get the full length headers in their and you don't have a whole lot of room from where long header end to one of your crossmembers then you have to think about how you want it because you can't go under your gas tank the way I did it is I went under my frame and under my bed then they dumped out in front of my rear wheels
