nitrous will get you more than that, won't affect gas mileage when not in use, and it will run you less then 600 buks.

 

true but that's for straight line racing and maybe some autocrossing. daily driving would be impractical for that/

 

Found some recent owners' reviews for this on Minkara just now. All pretty much say the same thing -- no low-end torque loss and torque seems to come on much stronger from 3k on with the engine pulling hard all the way up into the high end. Every one of them recommend it as a must have part for the Fit over any other manifold. Should also point out that they all have the thermo-wrapped version.

 

any comments on how much louder it is vs. stock manifold?

 

Nope, not a one that I saw -- all just mentioned the gains only. I'll watch for more reviews though, I'm sure others are gonna pick this up in the near future and post.

 

You think that's bad, try doing basic boltons for an S2000. Js header will run you at $1,200 and for gains up to 5whp

Ill prolly be getting the Js header and 50rr exhaust soon

 

I do agree that 1400$ is a lot of money for 15HP gain. But the original 84whp is too timid. I had to increase the torque and response. So I went for the classic I/H/E/P. It produces a noticable gain that you can feel and enjoy in your everyday ride, as is represent close to 20% increase in power!
And as a bonus to the increased flow, you get a lovely sound to remind you where your money went
