MOT and decat exhaust
How am I likely to fare? I have a decat powerflow exhaust with 1 box and a 3" tailpipe. Just wondering as MOT is today

most cars without a cat will fail a cat test.
ironically with mine the garage got it into spec without a cat as i didnt have the engine age proof with me that day. it was shockingly bad at idle but once the oil was hot it was inspec for fast idle test and just about held it inspec for the idle test for the 30 seconds. I was surprised to say the least.

MK2 V6 mondeo's pass with a decat, but it has two precats on the manifold, which goes to show, it doesnt even need the main cat, as the emissions are low enough with out it. so come MOT time, im not even refitting my cat

So if your car never came with a cat back in the day and it fails on the emissions today do you then need to add a cat? or not as there were build without them...

Bit more to it than that mate. Some retro fit stuff is shocking I agree but the units I have seen fitted to my brothers BMW are superb and don't dazzle, nor do those fitted to a mates Passat.

Although a car say from 92 may pass a emissions test without a cat, although it may have had one from the factory, but it's now removed and passes test, VOSA can still nick you for not having one!!

are you for real?
does it really bother you that certain places may let the emissions test slip?
whats the difference between having it fitted at the time of the mot to get a pass and then removing it, and having a helpful bloke that will turn a blind eye and giving it a pass anyway?
there are shit loads of places that will let it go.
would you really go out your way and report a garage for the above?

Yes I'm for real, and NO, I'm not at all bothered about the emissions, I just report mot's where any safety related aspect is skimped, I got the impression that was what the message reffered to, I've seen cars mot'd without even being in the garage at the time.
Cats for the most part can do more harm than good, increasing emissions due to more fuel usage unless "lit" ie up to temperature, and don't believe all this global warming crap anyway, it's happened since the earth was formed, it's a constant cycle of warm/cold, but a good way to screw the public/motorist out of yet more money.
The whole emissions thing is so badly run imo anyway, some old granny has a 20 year old car that puts out 3.5% co, and does 5 miles each sunday to the church pays Ł200 odd in tax, versus the business user doing 100K a year versus 250 miles pays NOTHING due to his car being "cleaner", I'm sure the carbon output is vastly greater from his over a year.
But to confirm no not at all interested in "helping" cars with gas part of the mot, and yes I have even reported the guy who did the mot on a car I bought from him, then again if you were the one crossing the road in front of this car with defective brakes you might be glad I did, I've also had a ex mate pass a car with NO rear calipers, a Fiat Uno turbo, they were seized and pricey so mate mot'd it and sold it, to a lady with three young children, don't expect me not to be "for real" or apologise, I've not spoken to him to this day, and yes the tester was prosecuted and YES I gave evidence against him.

i can understand doing it on more serious things and would consider it myself but rightly or wrongly i got the impression you would report a garage over alittle help with emissions checks.
if i have this wrong then i appologise

If you buy a Suzuki,with a cat,it pretty much always passes emissions as there's no data available for them,top secret.it has to go through a general pre cat test instead,I'm sure a few Mot testers on here can confirm this.
That new Mot test includes a lot of interesting things like if an ECU has been altered etc,fuck knows how they test it,but cut springs,excessive lowering etc are all on the menu,although the government are seriously considering a 2 year euro style test which personally I think is a bad move,look how quick a car,fords in particular can rot in a year,after 2 some could be condemned!!!!

It came across to me as well that tabs would report for emissions only but I know he's commented on a few threads before regarding undeclared engine conversions etc which is a fair enough thing to do as a lot are technically uninsured,note I said a "lot",not all.

He will no doubt be well chuffed when VOSA stop you at the roadside then remove his MOT licence for him. Happens up here all the time.
There is a real easy way to solve this problem. Fit a bloody cat. I think we charge about Ł300 to supply and fit a 350bhp capable one to a 3" exhaust. Job done, for good.

surely they would need to prove that the cat wasnt inplace when the mot was carried out

Plus, some of these testers are plain stupid. They do daft things for mates like this and let lots of other stuff go as well, then VOSA look over the car because you failed an emissions test and boom... "Who the hell MOT'd this?"
The new tests are much harder to dupe as well, quite interesting what they are up to now.

alot of the MOT items that are 'supposed' to be happening are all speculation, VOSA have had their collars felt massively in the last year or so, any tester who tests on a regular basis should have reallised that, just take a comparison of the manual, and one instance is brake disc condition, there are lots more that I could mention that would have been a point blank 'reason for rejection' which have been removed totally from the manual.
From what I can read between it, and from our local area office a case has been tried somewhere and VOSA lost big time, resulting in a lot of changes to the test.
Whilst I personally think the emissions testing is massivly flawed, your car came out of the factory with it if needed, just keep it in, or, if you are modifying the vehicle, the modify it properly.

I used a 200 cell sports cat on my Mk2 ST when i had it. Bought it second hand off ebay. I have no idea how old it was, but it worked a treat and passed the MOT every year I owned the car. I was going to go for a 100 cell cat but was advised that when new they are ok but after a while they may not hold the emissions in spec and therefore fail an MOT test.
