Catalytic converter touching np208...

look at post 13, which is unchaged. I state a majority of aftermarket converters dont last.


I dont mention "all"

another link proving i know what im talking about.


it isn't black and white if im replying to your statement here

I agree on price, you probably pay for what you get, but none of us have the capability to say that failure is due solely to the construction of the converter.

And me posting the first link is proving that I already have the knowledge that converters fail to numerous causes.


Im glad jarhead knows what he is talking about. Maybe because it says "mechanic" in his occupation.

I'm glad someone knows what they are talking about, because making a blanket statement proves that you don't.

Stop trying to defend your post, it's unchanged and blatantly obvious. You don't have to put "all" to imply it.

"The converters" and "they" without stating actual failure rate of all made, or failure rate by brand, implies all.

I don't know why your hung up on 2 year old data, it's not like that stuff hasn't been available (and read) until now. In any case, by that articles statements, and apparently your belief, as soon as the warranty or federal requirement is up, the part will fail, and thats acceptable. At that rate, pretty much every new GM is dead after what, 3/36?

Heck, disregarding that 3/36 argument, lets look at converters alone. According to what you believe and are stating, (hey, I'm just using the article that proves you know what you are talking about) after 80,000 miles, all OEM converters must no longer work. Is that any kind of logic? Does that allow us to therefore say that if aftermarket converters only have to work for 25,000 miles, they will? That must mean that even if an aftermarket converter offers a lifetime warranty, since the REQUIREMENT is for only 25,000 miles, thats all ANY of them are built to work for.

Even that article says NOTHING about converters failing at a set point, because there are way too many variables affecting life and operation no matter who made it. Period.

I dont need to rely on two year old data. That link is just an example of my experience and other mechanics and to backup what i stated. That is like you pussying out an argument by saying. .... "john a mechanic that worked on cars for 30 years retired two years ago, his experience of CAT systems is full of it, because he hasn't touched a car in two years.


The argument isn't about warranties It is how long do aftermarket exhausts last. And my first post was about comparing cheap converters to OEM converters. But you think the quality is the same.
a 100 dollar converter is the same as a 400 dollar OEM converter


No one can prove when anything on a automobile will fail. That is why there are tolerences in engineering and statistics. If you read the bottom of the article. You would have noticed that aftermarket converters have a hard time passing the next emissions test. And the same will be noted by a lot of mechanics in the field that fixed a vehicle that either failed or needed a new converter for an IM240 test.


But you have a hard time accepting that you dont know everything about automobiles. It hit you hard learning that not all catalytic converters are created equal.

But go back to believing your a mechanic on the internet and change your sparkplugs and oil on the weekend when your wife is gone shopping for the
day.


Next you will tell me aftermarket HEI ign modules last longer then GMs.
