Two questions one about coolant the other about a rattle

The catalytic converters are warrantied for 8 years or 80K miles FYI

Might be able to get Nissan to cover it depending on when the car was purchased.

I still have my stock cats with roughly 50k miles on them but I swapped those out for Berk Resonated HFCs a year ago and now running ISR Resonated Test pipes since KS doesn't do emissions tests. (Thank goodness!)

Long story short, I did a tune while I had HFCs on that ran stupid rich and actually burned out the cat to the point it sounded like rocks and I was misfiring badly at highway speeds. Since the test pipes I've been good and don't have to worry about any blockage issues anymore since there aren't any! If you're wanting to go the semi-loud route I'd suggest test pipes and a muffler but obviously CARB compliance is another factor into that decision.

Lucky lol, Cali has got the worst emissions laws

I am fearing a poor running engine that might cause something to break so I want to get this fixed ASAP. So I guess it’s safe to say my car is running rich then?

I saw that on the manual. I was thinking I might see if I can source some oem air boxes to install on the car along with my factory exhaust. I’ll see if Nissan can warranty it. I have a feeling if they see the aftermarket stuff they might not even have a look. I haven’t called around but just a quick online search has shown me these cats are 590 to 790 a piece.
