just a bunch of bolt ons. pro 5.0 shifter 65mm t/b c&l cold air kit underdrive's eibach pro kit lowering springs i was told by the previous owner it has an aftermarket fuel pump and 3.55's too. i've never driven one with any other gears, so i can't verify it. equal length shorties with an offroad x-pipe and 3 chamber flows, i hate this exhaust and then the stuff you can see, like the 2 1/2 inch cervini's cowl and silver cobra r's.
