Here is a pic, sorry for the poor quality.

Thx for posting that pic, Will!

No problem man. Thanks for all your help and advice!

So i was thinking about this whole secondary O2 sensor/check engine light nuisance...

It seems like the problem is not enough filter before the secondary O2 sensor. so i was wondering, has anyone ever tried cutting out a small cylindrical piece of the stock catalytic converter "catalyst filter" and stuff that into the extended secondary O2 port? It seems like that would clean the exhaust better than steel wool and therefore greatly reduce the CEL occurence?

just a thought...

as you can see, they drill a very small opening to replicate the anti fouler method. I plan on stuffing some steel wool in there too. I will see how it goes...

Hey there, So did you stuff the steel wool in there? What's the difference in power since you added the Berk's?

I must say that after many miles my Berks are starting to sound like a test pipe, waiting for Mackins resonated test pipe

This thread is soooo old....dunno know why it's still getting posts. For what it's though, I have over 8k miles on my Berk HFC's with Nismo CBE and have not thrown a CEL.

That is good news for sure!! I do have another question. Any idea reagrading your horsepower gain with the Berk's?? Thanks much for the 411!

Nope, they were installed at the time with other mods. I am sure the HFC came in on the dyno with their rated HP gain. No steel wool was used.

Two of 5 videos on the mods:
