What cella re you throwing?

strange. Did you install catless or high flow cat turboback recently.

I'm curious to see what cel you are getting. I'm going to install mine this weekend.

P0171 (bank 1 too lean)
P1153 (O2 sensor ***t signal, blah)

Gruppe-S is working on finding the cause. I found another guy who had the same problem. I really don't want to have to pull them off, because the difference in power is huge.

ppl wrap their downpipes to mostly reduce under hood temps,

and those JDM headers look equal length, wonder if those jdm wrx's sound like inline 4s ;(

Has anyone tried wrapping their aftermarket headers??? What about wrapping their stock ones?? I figured wrapping them would help retain gas temps and velocity....Or maybe i am confused and wrapping is soley to keep bay temps down??

Mine are wrapped, and the car spools faster with them wrapped to the point you can notice a difference.

I got my XXTuning/GTSpec headers in recently. I haven't installed them yet. I will install them by the end of this month along with my ported and thermal coated VF34. By the way, the headers you see in this picture are infact thermal coated inside and out believe it or not....no dark purple welding spots. The coating on the header and VF34 exhaust side were done by Airborn(spelling?) Coatings and they do coat components for NASA. Also, have you ever seen an exhaust side brighter and shinier than the compressor side of a turbo?? Look....

Very good point.
