Anyone Installed Headers On The N52?

[solo_the_lad]

Hi all, I've been playing with the idea of installing a two step rev limiter on my z4. I then watched a video of someone who did just that, and then was bouncing off the limiter when his cat internals proceed to explode out of the exhaust . So now im thinking I might need headers as well if the cats will just melt anyways. Does anyone know which headers fit the Z? Also will I need to tune/ code it afterwards? Trying my best to avoid a dreaded CEL here.

I am presuming you have LHD so think you would be better off asking or searching Zpost on the Bimmerpost forum as you have much more choice on headers for LHD and yes a tune would be needed to make full use of the headers and the repositioning of the cats / lambda sensors
