THis is a "definetive" answer that people should just accept and spend 4k on .headers? It would be nice if the company who made them or someone who actually knows some actual data would give us some idea of what exactly specifically is improved, changed and the new sizes/shapes of the pieces of headers instead of you "most likely" speculation.

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
