Please explain to me how headers reduce back pressure when the cause of the back pressure (the restrictive exhaust pipes, mufflers, and tail pipes) is still there? Headers are only effective when they are run open or did you Americans forget that little detail? And then headers are only effective when the engine is being run at full power and high rpm; something street engines rarely (if ever) do.

Steel tubing exhaust manifolds do have their place in off road track racing events where mufflers aren't required but when used on street legal vehicles they offer no benefit at all. Just ornaments with a cool name and hefty price tag.
