thanks for the info guys.

for some reason whenever i search j's or j it says nothing found and if i do j's header just gives me every header thread. so if anyone else can find dyno on j's that would be awesome i know there are a few here.

I've always wondered how the Mugen AP2 header would work on an AP1 ... any ideas? I would assume that the AP1 moves more air on the top end, since it has more agressive cams and revs out further, so I would think that the higher-flowing Mugen AP2 header would work well w/ this ?

Dyno

I think it is worth mentioning that this was w/ Hayward ITBs, Toda Spec A cams (notoriously unreliable), Toda race head, Amuse exhaust (60mm) and an HKS header.

He also gained +20whp over stock w/ just a Mugen intake (makes nothing on dyno), Amuse exhaust, HKS header, and a tune.

Because of the design of the HKS header (it's a 4-2-1, but extremely long primaries, looks like a 4-1), it needs supporting mods to make power. Stage 6 doesn't have a dyno right now apparently, so I'll have to find a shop w/ a dyno to install the header so that we can see before/after w/ my K&N filter, J's exhaust, and Berk test pipe ... I'll try to get some measurements, too.

I'm actually using that for the itb thread . Besides the results from that dyno due to the itbs and toda race head, and tune.

is the j's SPL header proven on F22's as well?

I know j's says it is good for F20 & F22, but what have been the results from s2ki members?
Check back in the first post for the J's header. I added a dyno plot of an 06 showing great results.

Spoon - $1,300
Tri-y design. 45mm primaries. This header is just slightly lighter then the stock header. There have been reports of this header actually losing power. Spoon is a great aftermarket parts provider, but they may have failed with this one.
Just as I posted before in the old Header Thread. Spoon header report is not accurate. I dynoed on Spoon Header. 250hp on Dyna pack at Shawn Church's place. 2:02.5 sec at Button Willow CW#13. Tell me this is a failed product.
