Wondering if anyone had seen these new headers, very quality work. I think they are around 900$ shipped to the US. Will be buying a set and getting rid of my kleemann headers. Should have a before and after dyno also, and maybe some sound clips. They also come in two different collector sizes 70mm and 76mm I believe.
some have used an older generation bmw x5 housing which is little bit bigger and accepts our maf sensor. not sure about tuning, thats been the biggest mystery.

Oh ok, well it seems to work just fine with the stock MAF, and made plenty of power. I don’t think a barely bigger MAF will change anything.

Did those bad boys show up yet? I'm buying these also, very curious to see your experience with installation and fit. Someone else I saw install them took out steering rack to get the driver's side installed. Curious if you'll be able to manage without doing that.
Was checking out your 80mm throttle body thread, seeing that you're at 356 wheel hp I don't see why this (plus an exhaust) couldn't put you around 375...
BTW thanks for actually documenting your work and showing dyno numbers along the way... These cars are getting less attention, so your work and documentation is priceless... Awesome job and appreciated.
