I i were you i'd get a better FMIC, the greddy piping is 2.5 youd be better off with 3 inch piping. Look into a ETS kit or something along those lines. You know your gonna get literally NO traction right? especially with your A/C removed and battery relocated.

Oh, and get atleast 680cc injectors, your gonna be all over fuel cut with a 16g and 550s
