How mcuh of the system has been changed. If its just a backbox then the centre cat may still be in place. However my MY00 import RA only had one cat as standard from the factory (DP one) and had the same centre as the one fitted to the UK cars when they buy the PPP.

It looks like its catted but it isnt . If the whole system has been changed however it may be de-catted already . Changing the DP for an MOT isnt quick and involves time and effort and knowledge and from what I have seen, usually library of swear words . The centre cat is easier to put back and is a 10 minute job.

I have a 93 grey import and want to take the cat out! i have been told it will boost the horse power and sound mean :-> Problem is HOW??? i have a scorpian 4.5inch system on at the mo so dont really want to replace the whole system! think it needs a cat for the MOT though! can anybody help? please!

 

bob-your car has 2 cats as standard,one in the center section and the other is in the downpipe.

you have already lost the cat in the center section by fitting the scorpion zorst but you need a replacement(catless)downpipe to replace the cat in the downpipe you have at the moment.

best one for your car IMHO is the scoobysport one as it has the best flow from the back of the turbo.

makes a lot of difference and IMHO the best mod you can do for the money.

when it comes to MOT time just refit the old frontpipe

thats what i do.
