De-Cat for a 2.2 petrol

Post by no2lurch »

is it possible?

reason i ask is cos i want to get some more out of my car and surely a decat is the best bet first. however - i have a lambda sensor before and after the cat.

can i do it then?

i know the ramifications of taking the car for mot without a cat.

i'm more concerned with how the current post cat sensor will read after the decat has happened. will it read the o2 level to a point of the cars ecu becoming confused and then throwing an error code up?

Get a sports cat?
Usually cheaper than a conventional cat, not at all restrictive and will pass an MOT :)

if you have lpg you can bash the middle of the cat out and during the test it will still pass without a cat.

Never had an emissions test for MOT.

So long as it's not reeking smoke everywhere.

Every MOT I've ever had has involved emissions testing - I guess it's a petrol thing; diesels (apparently) don't get tested on emissions.
