Official Richard Holdener who wants to buy an Long Tube Header list - Toyota Yaris Forums

If I screw in the O2 anti-fouler will this header pass emissions test? I live in Texas and They will use my OBD2 port to check for emissions. So aslong as the header doesn't throw a CEL I will buy it later on.

The header itself will not throw a CEL-but the second oxygen sensor is an issue. If it can be fooled with anti-fouler then there should be no problem. If the header is run with a cat-then it will likely pass a sniffer test as well but the system is offficially for off-road use only.
