So I was looking at Summit Racing because I was bored and I saw a header that I have never heard about. Has anybody used this Xforce header or know anything about them? 4-1 stainless/ polished..1 5/8in. Looks pretty nice but I would rather have the weapon R race header.

 

Headers make so little difference on these cars that brand is looks more than function.. That brand seems to use nice heave flanges and looks like it has a resonator possibly to replace the cat?

Stainless for 225 bucks aint bad at all...

 

I agree that they really don't do much and wonder what kind of numbers we would get on a dyno. The price is right..also looks like people in Australia use these headers on wrx's and like them. I have just been looking to modify my wifes 07 fit sport because I can't leave a car stock lol. I drive a 91 Thunderbird with a full 94 Lincoln Mark Viii swap(engine,trans,suspension,rear and interior) I think a full exhaust,intake and a center console will make the wife happy.

 

Honda didn't leave much on the table left to get power without a full end build or tune +

Intakes and exhaust just make more noise on these cars unless you go deep and bump compression or go FInduction it is what it is..

I quit working on my wifes car about 15 years ago and my life is way better.. She can go rag on the mechanic instead of me..

 

I dont know about you guys but the 4-1 header adn downpipe and changing the axelback made huge difference on my fit. car breathes better and i have really good response. Maybe mine is freak motor but even all my buddys that have k series, s2000's etc all say that my fit pulls pretty damn hard and is very responsive. and it wasn't like that at all when it was all stock. SO to say it doesnt make a difference is just ridiculous...............
