I guess I can try the steel wool fix and see what happens...

Theres basically a tiny hole in one so that it reduces the exhaust it receives drastically. I'd imagine this plus the O2 design on the HFC/Testpipes would do the trick just fine.

I'm not really following either one of you. Why would you bother with steel wool or a defouler when there is no evidence that the Berk HFCs or test pipes throws CELs? (Unless I missed something?) I've used the defouler method before, when I ran Kinetix test pipes on my 350Z. But those things didn't have the extended O2 ports, and I regularly got CELs until I installed the defoulers. As far as I can remember, nobody has had an issue with CELs with the extended O2 ports, so it seems to me that you guys are trying to fix something that isn't broken. Again -- unless I'm missing something(?).

Just trying to prevent the CEL. A few people have said they got a CEL after several thousand miles.

Ah. Well then yeah, it doesn't hurt to be proactive. Either method would work. Personally I think it'd be easier to just use a little steel wool to buffer that hole more. One of the nice things about the defouler method is that it actually mounts the sensor back away from the direct path of the exhaust gases, but given that these things already have the extended ports that do that for you by default, mounting defoulers on top of those would be redundant.
