All right lets go. I just bought a 04 F150 Ext cab 4X4 with the 4.6 for a good deal really wanted a FX but could not pass on this deal. It is the XL has 30000 miles, not a heritige.

I am going to get dual exhaust is true duals an option with this truck if so what am I looking at price wise? If not then what type of muffler or are strait pipes better performance wise? I am going to put some 285's or 305's on it so I need all the power I can squeeze out of it without hurting durability. I am looking at bolt on mods only.

also going to put a new air intake with more flow. which ones see the best gains?

Want to get a programmer also which one do you guys recommend?

Any hard numbers to back up the information would be great. And anything else I have not mentioned that could help with power

 

i got a 2006 f150 4.6L
For a programer i would go with the edge evolution, i got one and love it.

 

my fx4 (what is the difference between an fx4 and a fx4 anyway??? anybody???) has a K&n fipk, a jegs throttle body spacer, and an e-fan up front...breathing thru the fm 40 out back...it does very well!

im saving my money and working on my wife to let me get the edge evo...
