equal vs unequal length headers...

Ballcocks !
Restrictive my ****.
I'll grant you, I was very impressed after my initial "What's this ****" response when faced with the killer B headers,
but to say something starts to become restrictive at 350bhp yet produces this is laughable.
I've ran the GT spec headers for years and years, yes they're a compromise when it comes to cost over reliability, but certainly no compromise on bhp per £

I betw ith equals that 700 would have been even more that is the point I am making, as has been proved numerous times, it seems like a gain of 20-30hp everywhere is the norm for swapping from unequals to equals just based on the research I have done.
Oh and Martyn it will be back in for another mapping session soon on a billet s206 as that result was with a crack in the wastegate and exhaust housing it seems! So Im getting the turbo upgraded now, and will want you to fit the flat foot shift and CAL Switch too

I've offered Killer B the opportunity to do some back to back testing on my drag car, they unfortunately declined.
I'm willing to bet that the performance difference actually has very little to do with the nature of equal vs unequal and far more to do with the overall design of the headers and uppipe.
I'm also willing to bet that some of the difference we saw in performance of your car was due to the closed loop knock control strategy now being employed, as this allows you to get much closer to det knowing that the ecu will take care of it should it need to.
Ignition is power
More than happy to remap whenever you're ready !

Will I see much benefit from the billet upgrade on the turbo? I am actually quite excited about the flat foot shifting option...

All these people that like equal headers should just stop wasting there time with Subaru and just get an evo.If all you want is performance than sorry to say it but the evo has us all covered .P.S please don't shout at me to much you'll hurt my feelings lol.
