    Any performance issues?

    I've read posts about the lack of full pressure and having to rig the sensors to not throw codes causes more headaches than its worth.

    No issues. The one truck is boosted so it loves free flowing exhaust. The other truck is catless because the stock cats and exhaust were beat. The one truck has the urd o2 simulators so no CEL. The other one has rear o2 spacers to keep the CEL off because they dont sell the o2 simulators any more

    2”lift. Pretty stock.
    I’m having O2 sensor cel issues. What are the spacers for the sensors I see mentioned?
    Available? I have a new cat, put in by a dealer. Not sure if it’s aftermarket. Probably so.
    Thanks!
