I screwed the post a litte, the first pic should be the AFTER pic, the second pic shows the extractors after a days use
yer, that will always happen.
The color change is an oxide layer caused by heating in a atmosphere containing oxygen. This layer help protect the steel from corrosion and it also look badass!
Edit: Nice extractors by the way, are they the nu Power ones from ebay?

its cost 150 plus 30 bucks for postage so 180 all up, i definately felt an improvement in throttle response but not a real noticeable difference in pwoer, probably cause i still have stock cat and cat back exhaust. u can hear from the inside a tinny sound at around 3k revs or so not too loud, but i instaleld them myself, im gonna tighten the bolts a bit and see if the sound leaves
Did you put a new gasket in?

yeah all new gaskets, reused the bolts conecting to the cat, but bought new bolts to connect the extractors to the engine flex pipe (it came as two pieces)
