Decat would be illegal on a road going car.

How do you work that out bud? Ive owned a m3/nissan skyline/rx8 and ive had a decat on all those cars and moted each year..
If a catalytic converter was fitted as standard and is not present it is an MOT fail. Simple as that. Rule came in January 2012.

Imported Japanese has different rules on cats I remember reading on http://www.motester.co.uk/mot-forum somewhere......
I wondered because my P38 is a Jap re-import. I didn't find an answer to that.

Most MOT testers these days wouldn't know if a P38 was modded from standard or not in any case!
Like some don't know the ABS light only goes out once it reaches above 4-6mph!

That is why the tester said nothing then. Any vehicle that qualifies for a full CAT emission test MUST have cats fitted. That means petrol engines.

On a petrol it helps if you have just two lambdas before the cats so if you remove the cats it won't affect running. I am not in the UK so no cats just more power.
When I removed the cats the exhaust noise was up so replaced the cats with small straight through cans, they look a bit like sports cats too!!

Does the Isle of Man have different MOT rules?
Belay that, just looked and they do. Far more sensible approach if you ask me.

Even on LPG they start on petrol and can be run on petrol therefore they MUST have cats. If the car qualifies for a full cat test and cats were fitted as standard, it MUST have cats no matter what fuel it is running on. You will note fail for no cats in the UK MOT is in the visual inspection section. Regs were tightened 1st Jan 2012.
PS, don't read too much into what RPI say, they spout alot of BS.
Best way is something like a 100 cell cat. A decat V8 will sound great for a few days but will soon get annoying IMO.
