GB: Official DKF Section 1 Kit

[itdnwiwbp]

Good to know. So if I switch the resonators for the new incoming CATs and use my CSL headers that should be even better (as originally anticipated), correct? I really wanna put my CSL headers to use.

Hrmmm, I guess I'll wait for these then before i guy stock euro cats. I'm glad i decided to look here and read back, was so aggravated about my SEL, i was gonna buy euro's and sell this set.

Thanks for the info, and to DKF.

Tony-
I kinda think your current setup with the North American headers is better because the cats get nice a toasty up there so close to the engine. They work better when they are very hot. I really think either setup will just pass the sniffer. On my E46M3 I barely passed with 400 cell cats in section 1. I was sweating.

Glad to hear the good news! It's been a long road with a lot of hassle, but hopefully this does the trick. I've already turned off the SES/CEL with a tune, but would be nice to have it stay off without...

Stock headers and RE section 1. No secondary cats or resonators.
AHH!
I found where I posted my results. YMMV.

Thanks, that is great news! I do have an Evolve tune on it, do I have to put back to stock tune before taking it in for smog?

[StickMon]

Don't know, specifically.
If the result of the tune is an AFR richer than 14.7:1, it would be cause for concern.

He has a new CAT for us and that is what he asked me to post up and let everyone in the GB know.
I recently found out just how much work Doug has been putting in on his own dime ever since the question about getting the CATs to work came about.
I thought it was important to let you guys know as well.

When it became evident that only cars with a tune are able to get the SEL to stay off, he started doing some research.
First, he pursued the vendor of the CATs, and they were adamant that they supplied the proper 300 cell CATs, as ordered.
Doug, did not accept that as fact and decided to have a 3rd party investigate the CATs as supplied to the GB.
This 3rd party is a well known CAT manufacturer, and Doug paid them to investigate a sample CAT from the GB.

The result of this is; they determined that the CATs as supplied to the GB are not 300 cell CATs.
They are in fact 100 cell CATs.
As the 3rd part investigation explained it, a CAT cell count is based, not on the total cells in the CAT, but the cell density per 1 sq inch.
I don't know about you, but I had no idea how to tell a 100 from a 300 cell CAT
With this 3rd party information Doug went back to the original vendor and ultimately has them making a new run of 300 cell CATs for us.

I'm sure I don't have the full scope of what negotiations went on behind the scene to make this happen,
but for all we've been through with this GB I was amazed that DKF stuck it out and made this happen.
Everyone in the GB will be getting a new set of 300 cell CATs sent to directly them.
No need to worry about sending the old ones back.

Doug is asking everyone to email him at DKF to confirm your shipping details.
If there are any stragglers that don't happen to see this update in time for the free direct shipping from vendor; Doug will have their CATs shipped to DKF and they can arrange their shipping with Doug.
It's been an incredibly long haul on this GB with many vendor issues, but I really am happy that DKF stuck with this last CAT issue.
Apparently the new CATs are already in production, we should be hearing soon about shipping dates.

I emailed him. Thanks for keeping us in the loop.

[Blind32]

Awesome to hear! Thanks Doug!

[C-los]

Out of curiosity, did DKF give any type of ETA of the new cats completion?

[inTgr8r]

No, but they were supposed to be in production, so it shouldn't be too long.

[Beedub]

just an update, not been doing much driving as late winter is coming in, any dry days however I'm out, no CEL on my Fi car and theirs a definite bump in TQ particularly, the noise is incredible but added around 25% to the volume in total.

VERY happy with the pieces from DKF.

hows everybody else going ??

[Caddyshk]

The exhaust odor with just the resonators is overwhelming; 60's like... Bring on the Cats!

i get the same with the 100 cell cats.... exhaust fumes STINK. They are so small in Cat material, they don't appear to be actually cleaning up the fumes much. luckily the smell doesn't overly bother me.

[Beedub]

just wondering if anyone else has an update for the thread??? any new installers?? anyone got to a dyno??

[Steenos]

Whats the latest on the cats?

[inTgr8r]

...not a word.

i'll ping DKF to see wassup

[inTgr8r]

Good news!

CATs are in and ready to ship.
They will start shipping out in the next couple of days.

[Beedub]

what great news!! I'm praying mine passes emissions test with the 100 CELL cats..

[Steenos]

Thanks for checking! Great news indeed.

Great news! Can't wait to swap over, as my wife doesn't love the smell of the 100 cells Also may experiment with the tune to see if these are sufficient to avoid the CEL.

[Steenos]

Ok. I'm not trying to be a pain here. But. It's been 10 Days and I've heard nothing about cats shipping. I understand with the holiday season it's going to be a little slower. But I'd just like to be kept in the loop.
