Headers with 200 cel cats
Hello
When using headers with 200 cel cats such as arh and obx. Is there a problem runing the o2 sensors just like stock with/without a tune?
Will 200 cel cats be enough to pass inspection (sweden) which is visual, readiness test and car must be between oem exhaust values.
Will the 200 cel cat kill the o2 sensors?
I would like to have headers with eurocharge tune without having inspection issues.

Are you in sweden as well?
I thought no front cats would be a instat fail just by visual inspection, thats why i started to look at long tubes insteed of kleemann.
Is there a problem with having rear o2 turned off? I thought you would fail the readiness test?
Do you have any other problems with your headers?

That sounds great. What a relief. I might just consider kleemann then.
Do you run the kleemann tune as well?
Do you have the rear o2 connected to the exhaust and electric connector but o2 turned off with star or have you just moved the o2 sensor out if the way?
Where in sweden are you located?

Ok, sounds good enough. Yes, bone stock at the moment. I'm in the process of making up my mind on which setup i'm going to run.
Orginally i had plan on doing full kleemann with boost kit, header and later lsd but i was a bit scared off by the need of hacking up my oem exhaust. If i leave all the work to kleemann it's a bit pricey as well at around 26k dkk due to the weak sek.
Thus i started to consider longtube headers with ec tune and pulley. Most likely obx headers with cats and 83mm. Looked at american racing headers to begin with the obx clone seems to be very close to the real deal for 1/3 of the money based on what i read here. The whole kit is allmost half price compared to kleemann and the ec tune trough computer seems easy and flexible.
But i have not yet decided.
Do you run heat exchanger? In case, which one?

I've been scouring the archives and have seen some mention of it. I just PM'ed a member who said he passed with the supplied 200 cell cats. I have read the contrary and it seems that 300 - 400 cell count is needed. Also that the after market ceramic catalysts are prone to fracture and clogging and better off going with a metal catalyst....

Well, if one can pass with kleemann 200 cel should not be a problem. To my understanding people in the us had more problems with the o2 rediness test.
Heard about clogging as well but it doesn't seem to be too common? I guees you could weld in new cats if that happen.
Duccen, have you ever faild an inspection due to the kleemanns and which he did you use from froozen boost?
Quite a dilemma if i should run kleemann or catted long tube. People please shime im with your experince

Thanks. I got some serious thinking to do.
I like the kleemann but at the same time i really like the idea of having my stock exhaust intact. If i cut and weld myself the cost for kleemann and obx are about the same.

I will hopefully have my long tubes installed in around 10 days. I have 100 cell cats going in, no secondaries. I have a eurocharged tune for both secondary oxygen sensors turned on and another tune for having them off. I will try on first and see what happens. We only have a visual inspection here but I will see if there is a CEL.

Are the 90* adapters facing upstream or down? G sport Non-EPA, High or ultra?

I did not know that, I'm pretty new to exhaust mods other than straight bolt ons.
I'm very tempted just going long tubes with cats since that would spare my oem exhaust if i find myself in a situation where i need to switch.
Then the question is if i should go with the copies or brand name like American Racing. From reading here the copies seems to be real close to the real deal.

My plan is to go.... LT (copies)---300 cell cat--- secondaries--- resonator---mufflers. Using the O2 sensors turned on.

You might struggle to fit two sets of cats in there. Some good quality primary ones should be sufficient.
