Hi,

Car is due its MOT in just over two weeks and I was wondering what is the best way to get it through the MOT? As it has got a de-cat downpipe on it.

Is there any tips on how to lower the emissions to a passable level? I do have the cat downpipe so is it just easier to have my mechanic refit that before testing it?

Ta!

 

Call ahead...

Make sure your slot is open..

Drive it really really really hard!! On the way there!! Decent 15-20min drive
Get it tested for the emissions as soon as your arrive!

Usually Bingo!

 

As above, I was told by Extreme Scoobies when I had a de-catted classic some years back to gun it hard to get it nice & hot & should go through.

 

take it to a tuner such as api, subaru4you, powerengineering and they will get it sorted for you

 

put the cat back in :P

 

No way a car will pass with no cat at all, no matter how hot it is. Some cars struggle to go through with just a sports cat fitted.

 

some misunderstanding here.....
You can get a 2nd cat in the centre pipe, but the problem is that it doesnt get hot enough, also some sports cats are not actually that great, so with these two scenarios you need to take the above advice, and even then it only may pass.

Without a cat, no matter how hot it is, you have buckley's!

 

If the garage is legit then your car will not pass the emissions test with no cat. You will need to re-fit the cat down pipe. Even if you still have the centre cat it won't pass with just that.

 

Mine has passed at a main dealer (Ford) failed first time on emissions but passed the second, ran some redex in it and the engine was piping hot when they did it, passed easily. I have not cats at all ;-)

 

similar to above.. mine went through with some forte treatment in the petrol tank..

 

Mine failed with a centre cat in it. It was easier to change than the down-pipe. I had to put the catted down-pipe back in to pass. I suppose each car is different.

 

Find a friendly mot tester like me!!!

 

get friendly with mot tester and back another car up with a cat in!!!

not that i would ever do that for anyone!!!

 

If you get one that wont mind giving it abot off revd thro test it will help. Normally scoobs are good at emmisions, If not Forte emission cleaner and a good run may do it,

If it fails re test it with Cat on mate

 

mine passes every year with just the centre cat,

 

As above , find a local MOT station , take the guy some beers and explain the situation. Like I did. And im sure u'll get a pass
