Looking for a header

I have a Bimmerbrakes header on my car (3.0) but you will get a CEL.

There are work arounds out there to eliminate the CEL but I have not heard if any work.

That's what I was referring to
It fits perfectly
Get it coated first it really reduces under hood heat.

Did you get the GEN3 M54B25/B30 performance headers for $276 or the SS M54B25/B30 V1 performance headers?

Gen 3
After talking to them the only difference was that they had relocated the O2 bungs to a "better" location for ease of sensor install in the performance header........I had no problem with the sensors.

Sorry I misread that, so gen 3 and the SS are both supposed to fit the 2.5 M54?
