It works, don't hesitate if you need one buy it now it works.
Works, I'm 80 miles in and my check engine light hasn't come back on, and it passed smog.
Very Good!
Bought both because of space constraints. Ended up using the 90 degree. Installed fast and killed the po430 code. Installed on 05 Toyota Avalon 3.5l. awesome product for anyone that has to pass emissions testing!
Repaired Catalytic Converter with straight through geometry but RPMs would pulsate during acceleration. Mini Cat on o2 sensor on CC stopped pulsation after 10 miles of ECM learning. Now runs just like new!
Packaging was solid - resealable bag + box. Quality is good, installed easily and fixed my P0420 code right away. No more check engine light! Would buy again.
The exhaust manifold with the integrated catalytic converter was an exact fit for my car. Not only was the installation process a breeze, but my car also passed the emissions test with flying colors. The build quality is exceptional, and I expect it to last for many miles. A fantastic replacement part that meets and exceeds OEM specifications.
I bought these manifold catalytic converters for my car. They are high quality and fit perfectly. Easy to install and solved my emissions issue. Fast shipping and a fair price. Highly recommend.
Just as advertised, no surprises. Very fast shipping.
Fits perfectly and makes a real difference—exhaust flows much smoother and the car feels noticeably more powerful.
Unfortunately this O2 extender did not work as described. The check engine light came back on after just a few miles of driving. Very disappointing and not worth the trouble
Hello,
Sorry to hear the CEL came back. A few common reasons are:
Your car may have multiple downstream O2 sensors but only one spacer was installed.
The spacer may not be fully tightened, causing a small leak.
The ECU needs to be reset and driven a few cycles to relearn.
The O2 sensor itself may be faulty.
Please check these points and let us know if you need more help.
Best regards,

Great shipping service and parts are exactly as described. Thank you~
Mini Catalizador O2 Sensor Spacer CEL FIX P0420/P0042/P0430 Code Universal (90 Degree)
Worked slick easy install and been about 500 miles and no check engine light back on and cats are empty.
Perfect! Took care of all my needs
Excellent thanks very much
At first, I was pretty skeptical about this O2 bypass. But when it arrived, it felt well-made and screwed perfectly onto my NTK O2 sensor. It’s been three weeks now with no check engine light, and the car runs smoothly. Just be sure to clear the codes and install it on the O2 sensor located after the catalytic converter.
Installed the 90 Degree Mini Catalytic Converter (SKU: C206-A001-HWP) on my 1999 Silverado 1500 V-8 due to limited space around the sensor. The original O2 sensor was larger, but I replaced it with a smaller diameter sensor from AutoZone that fit perfectly—no drilling needed. Installation was straightforward, and I secured the wires safely away from the pipes. After resetting the system, the P0430 code never came back. Shipping took 5 days, which was well worth the wait. Extremely happy with this purchase — such a great deal!
Great seller — fast shipping, fair price, and excellent quality product.
Cleared the code and it hasn’t returned. Very satisfied.
I’ll see how it holds up over time.
Quality built. Made no difference with my code
Hi, thank you for your feedback. We’re glad you’re satisfied with the build quality. In some cases, the P0420/P0430 code may persist if the downstream O2 sensor or wiring needs attention, or if the ECU requires a few drive cycles to recalibrate after installation. We recommend checking the sensor and connections to help resolve the code.
This is a well-made product that I'm sure works on many cars, but unfortunately not on my 2013 Subaru Forester. I was trying to get rid of P0420 code so I could pass NYS inspection (after already replacing the cat and both O2 sensors). It fixed the P0420 code, but caused a *different* fuel trim-related code, so I still couldn't pass inspection. Apparently, this is a well-known thing with 2005+ Subarus, because they also use the downstream O2 sensor to adjust fuel trim, in addition to monitoring cat efficiency. I ended up using a *single* Dorman 42009 Spark Plug Non-Fouler as an O2 sensor spacer, and that took care of the P0420 code without screwing up the post-catalytic fuel trim reading, and I was able to get my car inspected.
It actually works, it is work getting, especially when it comes to getting rid of that check engine light.
