Hot Rod magazine did a dyno test on how the "dents and dimples" we sometimes put in headers affect power. I was shocked to learn that it made very little difference even when the pipes were smashed to the point where they were half crushed
I'm calling "bullshit" on that article..run the car down the 1/4 with those smashed headers..then put on ones that aren't smashed the car will run quicker with the un'smashed ones..I saw the video of that those 2 are a couple of clowns:rolleyes::rolleyes::rolleyes:
