i disagree with the whole pipe thing. do you guys acctaully have that pipe? proly not right? well i do and i have the header and both of them together make a difference, its not just the header, and if you dont want a performance upgrade then dont get those, i was just thinkin that if you want raceready then your gonna want faster and quicker. but i think your wrong about the pipe. if you compare the stock one to the rmp i showed, its gotta a couple differences, such as the aluminum, whcich looks cool, its also a single chamber, and for sure it gives out more power.
