OK, so I installed the header up-pipe combo from Meagan today. (on 07 wrx) What can I say, patience is not a virtue of mine
I can always yank it for coating when I have better money. At least I'm honest!
Anyways, I'm kinda stumped. The throttle response is night and day and there is definately a bit more pep. It feels like I'm driving a big cam'ed V8 though! It shakes and idles at like 500rpm now and feels like it's gonna die when I am trying to stop. (it doesn't really die) No CEL, nothing to indicate anything wrong. So why all the shakes? Is this just a werks with a header? Just deal with it? Also, when did the up-pipe start coming cat-less, stock from Subaru!? You can shine a flashlight and look right through mine.
