People who want to know a mod actually turns out the promised power is somehow a troll to you-that is fine. Buy mods blindly like a ton of other people
I don't think anyone is suggesting that we (M3 owners) blindly purchase the product with no numbers to justify it. The headers aren't even on the market yet. They are, according to the title of this thread, in development.
Can you give the manufacturer a chance to finalize the product before they put dyno numbers out to the public?
