I don't recall anything about letting you know that I had your cat on the ordering info, but just may have not noticed; the exhaust I bought was the Quiet version for those with high-flow cats and headers. Only one O2 bung in the front pipe, and yes, to get the sensor to clear the frame with the short extender, I had to roll the pipe to the driver's side. The long extender has no chance of a fit.
I'm in St. Louis, MO, so a bit far from you; also, my normal phone can't call that number (it's pre-paid), so I have to use my other phone, which I don't have with me at work. How late in the day do you answer that phone number?
Deep, steel/sand, loaded except standard radio and no smoker's; #08974
