I been looking at the Evosport Headers as they are a basic swap out of the stock units, so downpipes dont need any mods... which is handy, esp if you want to bring car back to stock at any time.
You will need a remap to get most out of them ... or so I am told...
The Kleemann are nicer in that they are larger diameter and have a better / longer collector which should be worth a few extra hp, but requires mod to down pipes and this is a bit of a pain if you want to bring car to stock at any time.
Reckon either is worth 15-20hp with mapping ...
Curious if the reduced backpressure is problematic but think thats what the remap helps remedy... mbe the guru's can chip in ?
