Sounds good, Gallardo Rosso! For reference, I think the part number we're talking about is 04 40 01. My headers have this printed on an attached decal.

I haven't fully researched the O2 sensor placement yet. What isthe rear sensor used for? We do have emissions testing here, so I'm hoping to pass with the SS cats and some Evolve tuning magic.
