Who would want a 4-1 header?
I have been talking with the same man who is bringing this goodie to the forum. RC000E will be able to make us up some custom 4-1 headers at a very affordable price if there is enough interest. A good 4-1 header can give gains of up to 10-20 HP over the best 4-2-1 header out there.
I will be able to get some accurate pricing once I see how many people would be interested with money ready to go. If we get this past the idea stage, I will be dyno testing the prototype on my build and will be able to give everyone a good indication of this headers performance compared to a 2.5" SSAC header.

I'll start the list

2. Keo

-Will it be stainless steel?
-Would it include an EGR bung?
-Are you saying 10-20hp on top of a 4-2-1 header? Now that's pretty cool.

If there would be a 3" collector rather than 2.5" then count me in... that would be sick!

I could be interresting, but I must know an average price before to confirm (because the shipping cost to FRance, will be more expensive than USA)

10 HP??? that is all you will gain, i don't understand why waste the time. i would just run no manifold, you will gain the best flow. if you guys want to get 10 hp, why not buy a tornado?

Is this guy serious? 5% is a nice bump in power I'd say...

Hmm, maybe you should run no manifold and let me know how it works out for you. Make sure to make a video of it and post it up on youtube.

p.s. what you said is quote worthy.
