De-Cat & passing an MOT
 

Anyone else done it? I was well shocked when I got the call last Saturday to say my car JUST squeezed through :O:O Didn't think it was possible but I ain't complaining :D:D

MAFFA

did you take all the cats off

I read on here a couple passed thru, which was surprising. Mine old 98 went thru with a decat, after the guy had a tenner off me for a few beers :D

It's not had any on it for about 3yrs :)

MAFFA

I didn't even have to bribe the guy :D. He actually took the MOT more seriously than I thought and failed me first time around for a power steering gaitor, no rear fog light connected and a tyre!!!

Still passed emissions tho :D

MAFFA

Thats encouraging... mine is up in Nov and im very worried. Full decat, custom manifold, no rear fog light working.


With the new MOT system being bought in..... mayb even beer and back handers cannot buy a certificate?

Where there's a will there's a way....that's my philosophy :)

if you know the garage whos to say you didnt fit the Cat for the day? Just get the readings from another car for the logs

Got a full decat on my classic and its passed the MOT for the last 3 years with no problems.:norty:

I keep trying on mine (MY97) Always a shade over...but it soooo close its silly..last time it was 0.2% off on the CO :(

Known plenty of cars which are not Subarus with decats that pass with ease (if they are running properly and are in tip top shape).

Yes, my decatted RB5 also passed the emmissions test without it being 'rigged'. Was funny watching a bunch of MOT testers figuring out how the car did it!

A pass, is a pass, is a pass! :D

Couldn't agree more :D

Damn....mines got a full decat for the last 3 yrs and it costs me a backhander every year!! Can't get the bloody thing in spec without the cat'!! How do you do it??

Gav.

Absolutely no idea? :D

My guess is the only person who would have a vague idea would be my mapper :)

Before moving 250 miles away it was mates with garages but now i'm kinda winging it :D

Apparently taking it for a drive and getting the system good an hot helps !! and test immediately.

Mine was only driven a mile down the road & then it sat for an hour :D
