The converter is nicely made, it welded in very well and was a good fit. It cleared my code for down steam 02 sensor. I can't say anything but good about it but need to see how long it lasts for a solid opinion. Magnaflow offers a heavy metal version that has better catalyst that may be a better choice for longevity. I did not know this before I bought and installed mine.

I purchased this converter for my 97 Toyota t-100 because it was less expensive than the OEM. The fit was fine. The 02 sensor was farther down the line and did not affect the install. The sound is very loud. Too loud for me. It is so loud, I had to check for an exhaust leak. No leaks, and very noisy. Also the 02 sensor/engine light came back on within a few hours.

Beware of Universal Catalytic Converters
Beware of Universal Catalytic Converters
Submitted 2013-09-21
By Davedrama
From Aurora, OH
I suppose this is a good value if you just need a simple converter with no oxygen sensor to worry about. I had to return it because my Jeep uses an oxygen sensor that screws directly into the converter. This unit has no such port. I was told by the mfg. that I would have to cut into the exhaust pipe and weld in an O2 port. That's above my pay grade. So I found a direct fit unit with the port already installed.
