I am looking at O/R H pipes for the Mrs' '06 GT. If I have the X-cal 2 tuner can I turn off the O2 sensors to keep the CEL from coming on or will I need MIL's? THANKS in advance.

All you need to do is turn of your 02's with your tuner and you'll be fine. I've got the O/R H and flowmasters and haven't had a CEL since.

Does it smell bad with the o/r h on it or is barely noticeable?

For the first few miles the smell is rather strong but it's only because the paint or coating is burning of the pipe. Unless you have your windows down and are sitting at a red light you'll never notice it.

Call your tuner and find out he already turned the rear o2 sensors off in your cai tune, alot tuners will do this. I found this out when i called fred at evolution prior to installing my o/r h-pipe, he assured me the rears o2's where already turned off in my 93 oct cai tune. If not you can always turn them off yourself in the adjustable parameters section in your xcal 2.
