I know of the need to remap the car with the OE headers removed, but I have no intention of adding replacements on their own. I was thinking about a new turbo unit and what gains I would get from such a turbo and as can be seen from the above (level 4). headers would be required along with a host of other things. It was just that I didn't know what headers were, which I still don't, not really, hence the reason for the post initially. I'm going to stab a guess at it and say that headers are the pipes connecting the engine block to the uppipe through which. exhaust gasses flow. In other words, the first point of exit for exhaust gasses.
