Metal Cat

Looking for an aftermarket cat and found this. http://www.metalcat.com.au/. My question is if they are euro 4 compliant does that mean the O2 issue is no longer an issue?

I don't know, but my advice is to ask a muffler expert like Midas or Macs Muffler Mart

Ok, it's my day to be dense. What's the O2 issue?

the problem is the H18C8 mixing with the O2 and making some CO2 and some CO. Along the way some S met some O and had an inappropriate relationship, and it was later discovered that not all H18C8 liked mixing with the O2 and so journeyed on its own.
The story continues in chapter 2

The O2 sensor on the cat. FG requires a tune to stop the engine warning light coming on.
