People say headers aren't very much bang for the buck....even heard of people running turbos with stock header. If it's true that they all do the same then I'd go for the cheapest one with the highest quality.
Well already I have the AEM Cold Air Intake, and underdrive pulleys, both have gave me quite a bit of HP. The headers that I was looking at were the Focus-Central Headers. To anyone who has a either of these mods, have you the lower fuel milage than before like I did??
id reccomend also a 65 or 70mm TB, and definately finish the exhaust,flexpipe and catback, a ported 2000 manifold, and cam gears, you could also do cams, what stage you get will depend on your future plans
I've also got a Ford Racing header and RT cat. It has definitly gotten louder and I can tell it made an increase in power. Haven't actually had a chance to run it at the track but will here in about 2 weeks to see what it'll do.
most of its wrench work. the header might give u some probs with cramped space. you should def get a chip next after your exhaust. as far as the shorty header, get what has a good warranty and a good price. for the most part, they are all very similar in design. just dont get pacesetter. but mac, ford racing, focus sport (if u can find it), jba and all those are decent from what ive heard. FC kinda is iffy with me but its ur wad. happy modding
I've heard that the performance chips screw with the cars computer, what would something like that do to a warranty other than probably void it???
Next question is beings there are quite a few of those chips out there all promising the same thing but then reading the reviews on them, they all have there problems, and there down falls. There is the Diablo, Jet and others that I can't remember off hand, which one is the best for performance and the wallet$$$
