We have a couple sets done and 2 more shipping soon. After we get feedback from these customers we will be releasing more information. One set has been installed and will be at the SEMA show next week. There are pictures on instagram of the install done at Project Import in California.

Dynos, pricing, pictures and other information will be posted as soon as we have feedback and finalized the product.

I've driven and dyno'd several header equipped ISF's... and I don't see them making any power over gutted primary cats, for whatever reason. Don't see it on the dyno, and don't feel it on the street either.


BTW, if you are comparing dyno results, and not publishing the corresponding A/F ratio graph, then the results are meaningless, because you can easily get a 30hp variation with our cars on the dyno as a function of intake air temp and coolant temps (which influence AFR and ignition timing).

So anyway, I don't want to be misunderstood, but I am just saying that it would be nice to see proven dyno results on these headers. Perhaps the equal length version will actually make some power, as I suspect that headers for the ISF (either due to unequal length or primary tube diameter) tend to result in ignition retard due to increased knock activity, perhaps due to lean AFR at certain cylinders.

The dyno's are indoors but the access still requires you to drive outside.

Will you be offering equal lengths for the ISF as well? Plenty of us still out there coming into the market for them.

Keep up the good work!!
