      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.
