I just put in the Berk test pipes and they sound great!

My Berk HFCs arrived today!

earlier someone asked what the inside of the secondary O2 sensor ports look like. Im assuming they were wondering if they are completely open or have an anti-fouler like small opening.

Here is a pic, sorry for the poor quality.

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...

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...

I just reached the end of this reading from Page 1.

It's like Jesse never really existed...

My Stillen HFCs are on the way.

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