I am looking for a header that gives a gain below 3000rpm..

any suggestion?


How's the t1r header?

Thanks

 

a header design with 4-2-1, Spoon or Weapon R. All others are bigger tubed free flowing 4 to 1 like the stock header hence greater power on the top side.

 

the t1r header shows gains through the whole power band if I'm no mistaken

 

cool
so..if i have the hks axle back, can i use any other mid-pipe beside the oem?



thanks

 

^ yeah it should fit. same with B-pipe and all that good stuff.

as far as low rpm gains. I'd look into the Weapon R header.

 

which mid-pipe is better with t1r intake and hks hi-power axle back?


People say there is fitment problem of the WR header..

 

well a lot of the people here have Megan mid-pipes. They seem to be pretty happy with it.

 

I am happy with my T1R. I only have a HFP axle back and a aFe drop in filter. You can feel the difference from about 2500. I can pull out of 45 mph in fifth gear, which I always downshifted for before. The wife says the car is a lot gutsier.

 

cool!
I am wondering how would T1R header + T1R CF intake + HKS hi-power sound like!

 

With how short the Fit's exhaust manifold is, I don't think there's enough length to pulse tune any low end gains. The lower the resonance point, the longer the piping has to be. a 4-2-1 header for the fit is 110% gimick. Any power gained from a 4-2-1 header in the fit is purely from larger diamer piping, not from any pulse tuning.

 

If it's a gimmick why does it work? It even shows on the dyno. So, either way it's 110% worth it. Larger piping takes away from low end gain.
