As of currently no one else sells headers or full systems ( that I know of) for the gen 1, but I'm hoping this combination will get me started with my mods on my new to me 01 fz1. Anyone have any input? The exup system is malfunctioning and I'd like to get rid of it to rid myself of future hassles as well. Next will be k&n air pod and ivans jet kit to fix the lean issue I'm bound to have after installing this mod. Is there anything I'm not taking into consideration?
