Do California 986's have extra smog equipment?

[Dlirium]

So, that's a good question - has anyone tried to do a CA smog test with the delete pipes in place? Unlikely I would fail visual, as the tech is probably not that motivated or familiar to check. I'm more curious how close an older Boxster will get to the HC and CO limits without the secondary cats...

For a bit more info, the early 986s (1997-1999) did not have secondary cats and were still California emissions compliant. As for mods, there are several aftermarket exhaust manufacturers offering lower cell count, higher flow catalytic converters as part of their exhaust package. For example check out Fabspeed's full exhaust package for a 986 on Pelican Parts.

Also if you're possibly interested in a '99 Boxster, let me know: '99 Boxster for Sale

Truthfully, it's likely just as easy and a LOT cheaper to swap back in the secondary cats if it doesn't pass with the primary cats I have in the headers. couple hours of wrenching and it's done...
