Haha,i said what needed to be said & got it off my chest.no one likes to be mislead & thank you very much

 

Agreed... It's a bad batch that they've been making right with customers.

I can appreciate that you're international, and even that you're upset, but all you've been doing today is complaining about parts like this and the throttle body (continuously bumping, as Higgs said)...

It could be a lot worse - look at the poor guy who had his engine blow up randomly. Just a thought...

 

I guess the truth hurts & no one wants to be clear here!
What was said might help others before purchasing misleading info about products.
Im not here to bump/dispair nonsense,just be clear to others thats all

 

A few isolated incidents is the 'truth'? That reasoning is flawed.

Furthermore, your anger comes from inconvenience. You could be shipped another set as they have done for others (which is far better than other vendors who have shafted customers for thousands of dollars), but you'd rather not get them re-installed, etc. Alright, that's your choice.

Now, you're dealing with aftermarket parts that try to fool an ECM. That's a slippery slope as it is. As you're already getting a tune, I have no clue why you went with mids instead of LTs which have zero issues. However, that being said, I showed you the marketing - it does not guarantee no CEL, as the E92 is so adaptive that it's very difficult to fool. This relies on perfect cat design to make more power while still not alerting the emissions control system.

You have essentially hijacked a thread with your own personal feelings and fired back at every sensible post made on here. The OP makes a great point, and shows reason - he knows that a friend is receiving a replacement set, he has shared that there is a known issue, and he is contacting ARH tomorrow. This is the appropriate behavior for this situation.

That's what a rational person does. An irrational person continues to bump and complain about something that's already able to be remedied, then lashes out repeatedly. I have shown you the errors in assumption that you've made, a la the website screenshot, etc. I don't work for ARH or any vendor here, but I'd say I do more than my fair share at making information available to everyone here, hence the tag.

I'm sorry, but this is just getting silly. Almost all of your posts are complaints, and it gets tiresome to see the same thing bumped over and over. That's what Higgs was getting at (in a polite way, no less - which for him is rare ).

The OP of this thread is handling things correctly - you need to do the same.

Let me leave you with one of our forum rules, before you undoubtedly snap back at a person who's just trying to give you some perspective:

 

Safe to buy these yet?

 

This is the problem... Threads like this cause misconceptions that just cause confusion, etc.

Call ARH and ask if they have this under control.

 

ARH just called to tell me my replacement Cats are on the way. I will post a status report as soon as I have them installed.

 

Build quality is good
But with the cel issue your taking a gamble 50/50..good luck

 

Again, misinformation - there is no gamble.

The post above you is posting factual information. ARH has called to replace the parts in question. We've gone through why you're unhappy, and you don't wish to have them replaced. That's unfortunate, but you're not allowing a remedy.

I've posted the rules, and I understand your frustration. But these types of posts are going to start getting reported after this.

 

Glad to hear it. Keep us updated, as the OP will be doing, as well.

 

Only time will tell

 

You're basically on the right track. Once a CEL is triggered, it needs to be cleared out/battery disconnected. Monitors are kinda like "breakers." When they're flipped, they need to be manually flipped off as they won't automatically return to opertation even if conditions are "correct."

The rear O2's often need a few good miles for the monitor to be active, usually steady driving miles hence the 100 miles or so without a CEL. As a general rule, NO health monitor will flip into ready until the engine has been warmed up to operating temperture.

 

I disconnected the battery & the cel went off.but after only 100 km of easy driving the cel returned.

 

Yeah, not surprised. The cats just aren't efficient enough.


Hgar99, interesting that ARH is sending you new kitties though. I've always been skeptical of Kook's "Green Cats" not throwing a CEL so it'll be interesting to see how your new NEW ARH Severe Duty pieces go about it.

 

I would like to thank the guys at ARH for taking care of my issues with the CEL after installing the mid-length headers on my C7.
I have now installed the replacement cats they sent me and after 300 miles I have not had a CEL . They sent me new cats, sensor extensions, and a return shipping label to return the old ones.
It is really great to deal with a first class company who stands behind their product.

Thanks for your help everyone.

 

10 days ago, we installed new cats with O2 extensions on my car and another C7. This fixed the problem. My friend has a couple hundred miles with the new cats and extensions and no CEL. I have 50 miles on my car and no check engine.

ARH came through and did what they needed to do to fix the issue.

 

My order didnt come with the 02 extensions,it wasnt purchased too long ago!! im an overseas customer, so shipping costs is the problem if warrentey is involved

 

Do you need to use the extensions for the front O2's? I know in some cars they're just zip tied down and they can just be released for more slack so you don't have to use them. I did that in my Mustang. I just don't trust extensions but that's just one of my quirks.

 

Not the wire extensions. These screw into the bung after the cat and pull the O2 sensor out of the exhaust stream.

 

disable them in the tune and remove the rear O2s. you already screwed your warranty by installing headers anyways.

and if you think an advertisement from a header manufacturer that says "will not void warranty" is accurate, ask them if you blow the motor and GM says "No warranty" if they will pay for another engine. ask a GM rep (not dealer) if they will warranty an engine with headers installed......

in today's day and age, you have to pay to play. and you have to do it right. a tune will make sure your car is running properly with these modifications. running without a tune is the fastest way to hurting the motor......not saying it is guaranteed, but I am saying you should be aware.
