Look for the wires hanging out from the rear of the catalytic converter on these 550i exhaust manifolds. Those are the rear o2 sensors. They're easy to get at from the bottom of the car.

West,
You are cruel.
Photoshop the gorgeous but expensive headers out of the photo next time. You are working against the rational side of me that says 360HP is more than enough.

Haha. I have another photo of the o2 sensor wire without the headers but it wasn't that good of a photo (too far in the distance). 360HP is more than enough!
