r/t has a better sound, I've driven both..

not much difference in topend performance, although the R/T gets better low end power, the ORP supposedly peaks HP a little higher

well if it was the R/T cat all gets re-installed. don't leaving anything out, and as far as i know you have to do the same with the ORP.

no, the first one needs to be installed, it gets the actual rich/lean readings... the second one is the one that is supposed to read a fairly constant voltage, thats why it can be tricked by a cheater.

I installed my supercharger at the same time and we put the new o2 sensor for the a/f gauge in the second one and just plugged the first one up because he said it would just burn out.

Where's the cheapest place to get an RT cat for our cars?
If you can't find one in the Buy, Sell forum, Mcnews and Hypnotic has them, and I think newedgeperformance does too

thats a different story, you've got a completely different tune set-up with the S/C, and since it's an orp you can have the front 02 in either hole. However, I bet you it's still reading as a front sensor.
