    Could I order universal cats and replace them? I’m very new to the tundra world. Excuse me for being so green

    Hard to know until its welded up if the computer will like the universal cats. Might as well just replace with an OE fit. Check RockAuto.com - they have options starting at $250. Also they are bolt in - no welding required.

    If they’re not rattling then just install a spark plug anti foulers on the o2 sensor and the code will go away.

    if it rattles you could move the rear cat up to the front position.

    either way give a call with any questions.

    Thanks for the post, I'm having the same issue after installing a complete MagnaFlow exhaust system on my Tundra. I'm no mechanic so I'm wondering how would I know which of the 3 included adjustable gas inserts to use with the Vibrant restrictor you recommended? I live in NY and have OBD II restrictions if that makes a difference. I put in all new Denso O2 sensors when I put in the new MagnaFlow system. Thanks for any help you can offer!
