I understand that you have the long tubes. Since there is no cross section upstream you should weld a bung on one of the tubes for the 02. The only downside to that is the fact that you will only be monitor one port. But from what I understand, unless you have a problem with a single cylinder there is not much of a monitering difference.
I still wanna know your other mods.

I left the 02's where they were in the MAC headers. Everything is working flawlessly. I don't see the o2's as ever being a problem, since the kooks headers are actually further away than these are. The pass side is prob. 8" further from the stock location. I did weld a bung in the pipe before the resonator for my wideband sensor.
Anyways, mods aren't all that impressive:
73 MAF, ZR intake, 75mm TB, ported inlet, 95 blower (outlet ported), raised top, 5% pulley, IC fan, 42lb injectors, 255lph pump, kirban regulator, zex dry kit (65hp), this full exhaust and headers, head work, cam grind, eec tuner, wideband data logger so i can tune everything myself. Some chassis braces and all the polly mounts.
Best time last year was 12.7 @109....on the old 2-2.5-2.25 exhaust.
Hoping for a 12.2 this year with my new exhaust and my front mount kit which should be done before summer. Who knows, I may even break into 11's.....
