Extra bungs are placed before the cat core and are used for wide-band tuning. You may never need them.

There are plenty of threads about this. The more of a brand's HFCs that are out there, the more likely you are to hear about CELs. Berk has probably sold the most to our community and theirs have the most CEL reports. ERZ has only sold a couple to a few of us on here, and there haven't been any CELs. FI hasn't outfitted that many of our 370Z community members, so the numbers are still relatively low to get a good feel for CELs. They make nice products with a lot of R&D though, so I imagine they've done their homework in preventing CELs. Good to know that 8k miles are CEL free for you.
