After the 6.0 swap I plan on installing some pacesetter lt's and their y pipe. Do most people still use their O2 sensors and cats? I'm not worried about being legal, i was just wondering what not running cats and O2 sensors will do to my motor, and how to delete them correctly without screwing something up!

 

tune them out or get some o2 simulators. with the lt's I still ran my front o2 sensors but deleted my back ones.

 

Here is what i posted not too long ago.. check it out..
