WaSaett 2.5" Catalytic Converter Universal 2.5 Inch Inlet/Outlet Universal High Flow Front Catalytic Converter with O2 Port Direct-Fit (EPA Compliant)

Works very good, used it on a Toyota probox n it sound smooth and quite. Very satisfied.

Have not yet installed it on my truck, but it seems to be built very well, has o2 port if you need it, i do not, size is correct

So far, everything is good.

You can tell right off that it's no where near as high quality as the original, but it doesn't appear to claim that it is. It's probably half the weight of my original one though which was surprising. Some of it looks to be the metal isn't as thick. Which means it might not be able to handle as much heat as the original will. The insides also doesn't look as thick as the original.Again they don't claim to be on par with the originals you will have in your vehicle. We ran some extra tests on the exhaust after the replacement and it was better than my blown out cat, and even gave me back the horse power I had lost. But the tests also showed compared to an original manufacture one that it wasn't doing as good of a job cleaning the exhaust. Might fail in some areas, luckily here we have no real emission tests so it wasn't a problem. O2 sensors didn't get upset about it and that's all that really mattered.It was half the price of a direct replacement, which made it worth it.

This worked great to replace a missing converter on a older truck, however this vehicle has no post cat O2 sensor, so I can't say how well it works. The exhaust smell is much better, and the truck passed inspection. Would buy again.
