Nope no truth in that
Ditto on this. Or is it true it will not effect the emissions test on a diesel ?
Diesels don't get emission tested
Result
Do they still do the thing where they rev it to the limiter.
They do a particulate test. Thats probably the thing you mean
guys just saved me a search thro an over crowded search result 
where is the cat on the ibizas, is it on the way down from the manifold, or on the flat under the car?
So it seems welding a wee pipe in , replacing the cat is a nice wee upgrade??? i know all the mot jargon, my mates an MOT tester, but never had a mate of mine, de-cat his turbo diesel
Forgot to put in here, does the de-cat end up with any warning lights etc on the dash etc?
cheers frazer

results befor i had a good map on and still had my cat on are
1.70
1.17
1.29
zero drift
max aloud is 0.10 actual is 0.00
mean value
max aloud is 3.00 actual is 1.39
last years results with better remap and de cat fitted are
0.09
zero drift
max 0.10 actual 0.00
mean value
max 3.00 actual 0.09
just shows havin a better map and a decat dont make your car smoke as much

Hope it goes well
If you get a chance take some pics and note down a basic guide as this could be a great cheap upgrade. A lot of folk do this on the x type 2.0 d without any probs.
I know it will prob cost but can you simply buy an after market down pipe which does not have a cat and fit that as my welding is not all that good.
it does put more pressure on the turbo due to the release in back pressure. But only in theroy to be honest, its more mechanical engineers that will tell you that as appose to mechanics. It will be very sooty though when booted and reasonably loud.
Diesels only get a standing emisions test and not a under load test so can get away with a decat.
