Yeah, should pass with ease. Have a look a couple of weeks back in General Tech. I posted my results there on my MY 98 with a full decat (FAILD, but only just realy) and then just a center cat, which it flu passed with ease. I would surgest using optimax (I understand it burnes more purely than other fules?) and a nicely warmed up cat.
good luck anywayz

hmmmm......
done a search
just been reading past threads with reference to this subject....
.....seems to be 50/50 pass/fail
i guess each car is different whatever the exhaust system
<fingers crossed>
hope mine passes tomorrow
<fingers uncrossed>

I'm going to be in the same boat as you in November. As Andy says, get it good and warm - boot it and get the exhaust nice'n'hot, as that's when cats are at their most efficient.
Good luck, and let us know

I did but www.subaru4you.co.uk had welded two cats into the centre pipe which you borrow just for the MOT, and 1/2 an hour after I was fully decatted again
passed by miles so I expect one would have sufficed (STi5)

Chris - if you have a problem, Elmer has a dual cat centre section he doesn't mind lending out, although he is based in Totton so you might have a bit of a journey - although it might be easier than swapping the downpipe!

Problem is that the scoob engine is "dirty" - it's getting a lot of power out of a relatively small engine. It hasn't been able to be sold in the US of A until the MY01 because of emissions, I believe...
Still, it looks like there's a good chance I'll pass with 1 cat. Excellent

My '98 passed it's second MOT yesterday with only the OEM center cat, they even offered to do the emissions test immediately after I arrived Although the car wasn't particularly hot when I got there.
With Oil temp @ 83C figures were:
Fast Idle : CO (<0.3) 0.24 ; HC (<200) 17 ; Lambda (0.97 - 1.03) 1.01
Natural Idle: CO (<0.5) 0.08

My MY99 passed on Monday with std BB and centre cat (I have a full 3" BPM so had to swap both), also std BOV fitted too.
Its been really weird driving around hearing birds sing, when normally I'm setting off car alarms
