Question WHAT CATS NEED TO BE IN PLACE FOR AN MOT?

What CATS need to be in place for an MOT on a newage?

I am buying a prodrive performance CAT but would like to know what I can remove along with this without getting problems come MOT time

Cheers

I think it is illegal to remove any fitted to the vehicle and therefore, technically a fail - but, one CAT should pass the MOT as far as I am aware, on emissions.

cheers for the PM joz (cannot reply via PM as your inbox is full) - bit far for me to travel but I do know someone that will turn a blind eye here but it's not a main subaru dealer and I wanted to ideally keep the FSH all subaru (good for resale).

Cheers

AFAIK you should pass with just the Prodrive sports cat. (I hope so as that's all that's on mine!) If it is a problem, then you could replace the 2nd cat for MoT time as it's a relatively easy job.

If it is the dealer you are concerned about chances are it will go elsewhere for MOT anyway. Get them to service it but take it to a different garage for MOT. Not like they are working on the car and the fee might be a bit less.

My '99 UK 2000 turbo passes every time with the centre cat removed (scoobysport mid section and backbox) - they only need the cat on the downpipe.

Mine's a '99 and yours is a bit newer - I think emissions regulations may be different for cars from 2001 on? I accepted the advice from this forum and got rid of the mid cat on my MY99, freeing up some extra horses at the same time and its now passed two MOT's as it is. Course, you could just keep the centre cat section just in case (which I did first time round, then sold it on Ebay) in case it didn't make the SVA test.

I'm confused on all these cats So you can't remove the one in the downpipe and pass an MOT but you can the secondary centre one? If you remove the one in the downpipe it will not pass?

As far as I know, for classics, the UK car has two CATS (downpipe and centre). The JDMs just have a CAT in the downpipe.

You can remove the UK downpipe CAT and still pass an MOT (could on my old MY98 anyway). But basicallly you need at least one CAT. My current JDM STi has a sports cat downpipe and passed the last MOT fine.

Yep, that's right and should pass. Mine has exactly that set up.

Yes and no. Remember an MOT only states the car was roadworthy at the time it was tested. You could drive out and have a brake light go 30 seconds down the road, get pulled and get a rectification order in theory, shiny MOT or not.

My MY00 has passed the last three MOT's with just the centre cat fitted. It's got a TEK 2.5 remap, so I think that probably helps a bit as well.
