In MY00 classic, is it in front or behind the cat? And which one? The one in the downpipe or the one in the center pipe? I care because I'm going to buy a sport cat-downpipe and decat center section and I'd like to know whether this setup confuses lambda's outputs. Thanx a lot, ivosh.

I thought there was just one at the top of the downpipe?? You can see it if you open the bonet and peer down behind the turbo.

1 only, top of downpipe, just behind turbo.

No problems with decatting or changing cats then. Thanks! i.

You just need to make sure the decat pipe has a threaded hole for the lambda sensor. Apparently some don't.
