Sounds your cat is starting to get clogged but when you drive for a long time, it probably helps to clear some of it out. If I was you, I would go on the highway and drive for an hour to see if you can help clean that out and I would Also put in this additive called cat clean in its like 30.00 a bottle but it would probably help in your case because it sounds like it’s not fully clogged yet cat clean is just a chemical that you put in The gas tank you can get it at any auto parts store but Walmart might have it cheaper

Problem is everyone the O2 monitor will not ready if you add the defowler and if in CA wont pass smog. CA emissions on some vehicles are too tight for example My 2003 Silverado is allowed 1004 parts per million but will not pass because it is sometimes putting out 1006 PPM so CA wants me to buy a $2500 dollar CAT which is made and sold in CA. So now I have to drive my 69 F100 which puts out 500,000 PPM but is smog exempt. Not what I want to do but what I have to do. What sucks to is the State can BIT flip your ECM to give a bad reading forcing you to buy a new car Yaaaaaay dictatorship

The O₂ sensor will still work when using a housing. It just moves it far enough away from the exhaust stream to not trigger the check engine light's P0420 cat inefficiency code. These rules are not based on science, cars of the last 30 years burn ridiculously clean. California emission laws are a corrupt money-making scheme between the govt and auto manufacturers. Defeating them is the American way! 🇺🇸🖕🏻

It depends on the car. Try one, then try to. I initially had two, and it was too far away from the airstream. The measurements from my O2 sensor were too low, and triggered another code, p0137, or low O2 voltage. When I went to one spacer, the O2 sensor voltage was within range.

This is illegal. You are not authorized to modify the federally illegal exhaust system. The O2 sensors will no longer get a steady stream of exhaust gas and will no longer work properly. Many states will fail you for emissions testing. Section 203(a)(3) of the Clean Air Act prohibits tampering with emission controls and manufacturing and selling products that defeat or bypass emission controls.

Assuming this is a Subaru... Subarus have a high rate of p0420 engine codes. Something to do with their programming a Subaru tech told me. Once a car gets more than 8 or 9 years old, replacing the catalytic converter on a Subaru is like half the value of a car. At the time of this reply, my 2016 Forester has a P0420 code. Dealer wants $4,200 for a new catalytic converter. Subaru requires the entire exhaust system from the headers back to be replaced. Non-dealer Subaru shop is about $600 less, still $3,600. To be any less than that, you're going aftermarket cat, which will only last a year or so. In the case of my car, it's probably just slightly less efficient, probably 95% instead of 100%. Why would I want to spend thousands of dollars, to slightly increase the quality of emissions my car puts out?

Well for a self claimed tech you’re clearly unaware what you are looking at. For starters he’s using an accessport to read the code and is running a catless down pipe so the issue isn’t fixing it incorrectly but the fact that a functioning 02 sensor would read incorrectly on a modified/tuned car. He never said to do it, in fact said it wasn’t correct. Before you call someone out you should educate yourself otherwise you have proven your lack on knowledge. Don’t claim to be a tech, own the fact you’re just running off with no clue about the vehicle. You have yourself a bad name but proved you’re incompetence
