Anyone cut out both pre and post cat on a 2006 and used O2 simms to prevent CEL and safe mode? I was told that on 2006 vipers the PCM looks not only at the O2 readings of the post cat but also the delta Temp to determine if cats are properly functioning and prolong cat life. If this is so, wouldnt the 02 simm have to send a default O2 reading as well as a temp reading to the PCM to work on a 2006 model?
Also, any companies that make a bypass pipe to attach to stock exhaust manifold upstream down to cat back system downstream OR did you just take to local muffler shop????
Anybody feel free to throw in your .02c on this. I want to understand how the system works. My 04 did not benefit greatly on power from cat removal but sounded like a mean ***** and was a simple replacement w/ O2 simms and worked great. Wondering about the 06 though?
