Exhaust Header Bash! Testing Power Loss From Dents

If you’ve ever installed a set of high-performance exhaust headers, then you’ve probably bashed those exhaust tubes with a hammer to get them to clear everything in the chassis of the car. It’s a super common problem, but people often worry about how much horsepower they are killing by dinging and denting those headers. This episode of Engine Masters presented by Amsoil is here to answer that for you, testing various levels of destruction of a set of Hooker headers on a 550-horsepower, 400ci small-block Chevy from Blueprint Engines. The result is shocking.

  1. With the technology today, it seems impossible not to be able to make a set of headers that fit properly.

    1. Hehe ja ser ut som det ikke har så mye å si men det er ikke slik d skal gjøres og det ene røret på forden er banket inn til halvparten av vanlig dimensjon. Ser jo grusomt ut også og meget lite profesjonelt når du bygger bil å gjøre d på denne måten.
      Irriterende som du sier ;-)
