Hey all, am pretty new to modding and all. My Z is completely stock. Am looking to push atleast 300whp or more. I've read about intake+exhaust mods, but i would like to know what is the best possible combos out there. Also the best bang for the buck. For an example, Berk's HFC + exhaust...etc) If you guys could lists a set of mods to help me out, that would be great.
