I just bought a Tomei UEL but these are looking awfully tempting.
I'm curious if the top end difference will be substantial with my Kraftwerks setup over the uel design??...

For the price those aren't bad at all, would be interesting to see they Dyno's on them compared to other "much more expensive" headers that are out there right now

I love mine. At first I was indifferent on the sound, but I love it now. I haven't dyno'd at all because I'm going flex fuel pretty soon.

This is dyno tuned on ECUTek with a Skunk2 Intake vs dyno tuned with a Skunk2 Intake and Skunk2 Alpha header. Car is otherwise stock.

That is damn impressive for the price, thank you for this

Was just coming to post this! Thank you @johan !

Vit is going to be switching back to E85 to see if he can't get 190+ out of the motor.

Anyone else running this header? Dyno results to share??

Sound clips?

I have one; I love it.

I'm running the stock tune, and the car obviously loves the header. It pulls much faster through the revrange than with the stock header. I did back to back vidoes of 0-60 & 30-70 pulls, and the car was repeatabily half second faster with the header. Unfortunately my phone bricked before I could upload them.

The collector is far from perfect, but it's a vast improvement over the lack of merge collectors in the stock manifold.
It's equal length, but the heads on our cars are not equal elngth which still gives the car a unique sound. It doesn't sound like a Honda, as so many other people say ELs sound like. It is really raspy with my exhasut, but that's a combination of the huge overlap and high compression our engines have, plus my resonator has blown out and is in need of replacement.

My exhaust does not drone, but drone is more based on the wall thicnkess used on your exhaust, and effective resonators.
I don't have any clips, as I'm waiting to install my overpipe and replace my blown out resonator before I film another video. I haven't dyno'd the car as there's no point IMHO unless I'm doing back to back tuning. My bolt on parts are more for the illusion of performance.

All in all I am extremely impressed with the header, especially at this price point. It sounds great, pulls hard, and looks pretty. The only issue I have had was with one runner which started hitting the drip-pan(under-tray), but a small dent made enough room for clearance. I'd rather not have done that, but I got my header used and it was supposedly a prototype.

sounds good. got my skunk2 header installed last night.

Not entirely sure i like the sound..at certain RPM ranges i like it a lot and at others (mostly the 1.5k-3k range) i am undecided.

I changed out the front and over pipe with the nameless high flo fp-op combo pipe as well.

So far no CEL. The header seemed to clear the belly pan with about 10mm of clearance. Keeping an ear out for any noise from that area though. The hardware and gaskets were a bonus.

Custom dyno tune incoming this saturday.

Mine is a 2015- FR-S by the way.

Its uel?

nope. Equal length

here's a before and after dyno of my car with the skunk2 header. BRZEdit tune

Who tuned it? Did they alter the cam angles?

VIP Performance.

Yeah they did. Why?
