Does the heat shielding in the top of the tunnel area come out so the extra wire could be placed behind it rather than between it and the exhaust? If not I'm not sure if the wiring would hold up if it's mounted on the shielding directly above the hot exhaust.

BTW I was interested in this because I have an aftermarket X-pipe with HFC's which has the secondary O2 bungs much farther down the pipe--why would you want to reposition the bungs behind the secondary cats on the factory exhaust--you thinking of cutting out the primaries or something?
I'm pretty sure the heat shielding comes out since that's how most install the short shifter.

I was thinking if one could extent the post-cat O2 sensors to behind the secondary cats, you could cut out the primary cats or get an X-pipe with HFC's downstream and not get a check engine light. It seems making a longer O2 sensor cable would be easier than trying to come up with some O2 sim- just not sure why the aftermarket folks haven't done this.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
