React catalytic converters from eurocarparts
Discussion
Whats wrong with this forum, its full of negativity and hostility.
I have written countless reviews on the web to help people over the years and never once had such a negative response. I only leave a review where i found i couldn’t find enough information myself before hand and feel the information i could provide would benefit future buyers of a product.
I have some noticed members here moan about the general hostility of members on here, seems they were spot.
TooMany2cvs i see you are one of those guys who doesn't read 'down stream o2 sensor graph was pretty much a carbon copy of the front sensor' or who wastes money replacing random parts without trying to actually understand the problem. Both sensors were working flawlessly. Why change a part that is not faulty, where is the logic? You carry on using your expensive method of randomly replacing parts until you fix the issue, and ill do it the proper way.
If a moderator deems my post inappropriate or an advertisement please by all means remove it. I was just trying to helpful. I think ill post somewhere else in future.

No, because the post one isn't critical to the running of my car, and it IS working fine, it would be £50 wasted. Plus I now have a spare in the form of the old front one and changing an o2 sensor is a 2 minute job. I never pay someone to fix my problems, no matter what the field.
Please show me the rule whereby you need to be an 'expert' to review a product. Also the definition of expert is subjective 'a person who is very knowledgeable about or skillful in a particular area.' Fixing 1999 Yaris hardly takes a great deal of skill or needs a great deal of knowledge .
Ill refrain from replying to you in future, you seems to be the type who likes to pick an argument where non needs not to be had.

This has been badly written, and suggests that the OP has used data from his ECU to prove that exhaust leaks can not cause high CO. Complete horse poop of course.
Air leaks absolutely can result in high CO. Any air that reaches the the O2 sensor will indicate a lean mixture to the ECU, which then increases fuel to compensate. Indeed a high lambda value (meaning excess O2) coupled with high CO is a common symptom of an exhaust leaks.
This is misleading to someone with little or no knowledge of the subject so OP should have said something like "Whilst a leaking exhaust can result in high lambda and CO values, the fuel trim data from my ECU suggested this was not the root cause"
I appreciate the time the OP spent writing his post, but if you are trying to put useful information in the public domain it must be written with your target audience in mind. Anyone with sound knowledge and experience of tracking down emissions problems probably isn't going to learn anything new, so don't assume that it's only going to be experts reading it who would be able to pick their way through mistakes and badly worded parts.
You're being pedantic for the sake of being pedantic, even the explanation you gave could be deemed misleading. This wasn't meant as a how to guide, it was just my experience with react cats with some supplementary information. It was hard to gauge what the target audience would be, hence i wrote....

"Please feel free to correct me of anything is wrong, i've missed out a lot of information i've deemed relevant or obvious. Also don’t rely on what some guy like me says on the internet, always do your own research and use multiple sources."
Anyway, the post served its purpose, it helped others. The react catalytic converters have a very short lifespan, but will see you through at least 1 or 2 MOTs.
