I just ordered the stage 1 and the high flow cat with the midpipe. If i understand right, i will need the O2 sensor things that dont make your light come on right. Im not sure what they are called. And if i do need them do they come with the package, i thought i read some where that they do.

Don't need them if you are getting the midpipe with the high flow cat. The stock sensors will attach to the new midpipe just like on the stock unit -- no fooler needed.

the only set back is your going to lose alot of torque from what i here.and everyone knows we need all the torque we can get some correct me if iam wrong.

Consider yourself corrected.

Yes, about the only things I noticed on Maurice's car when he installed the high flow cat and resonator was:
1. Increase in noise - mostly due to the Greddy cat back.
2. High RPM power dropped off slower.

Had little effect at low RPMs. The new cat allows him to tune "hotter" and therefore for more power than before, but right now he drives with standard "Stage 1" maps as he is still wringing more from them. He occationally installs "Stage 2" maps to test knock resistance, but we are still working out better control methods at that power level. These tests may change the circuitry for Stage 1 eventually as well. Better control means a better product and happier customers - especially Maurice. He drives what he sells .

especially Maurice. He drives what he sells .

that is a good thing!
