/6 Hooker Headers...surprise

Yep, people (and magazine articles) make all kinds of claims like that: Get 15 free horsepower by [whatever whatever whatever]. Usually no data, or a jiggered test, but always a big, loud crowd of True Believers who have a personal relationship with removed heat risers (or whatever) as their personal lord and saviour. And then the truth or falsehood question stops mattering, because it doesn't matter how much high-quality data you show them; they keep their fingers stuck in their ears and go "LA LA LA I CAN'T HEAR YOU FAKE NEWS LA LA LA LA".

¯\_(ツ)_/¯
