Now then... while Blue (145 T/Spark 1.8) is in intensive care following the demise of its waterpump hence cam-belt... I am going to sort out the upper exhaust which has been vexing me for some time;
The cat was replaced a long time ago prior to my ownership... and it appears to be from a completely different car.
The fitter "got round" the problem of it not having a flange that matched the OE down-pipe (flexi-section) by simply welding
the cat' to the OE down-pipe.
The exhaust is still sound (do you see what I did there?
) but my emissions are now a little high, the flexi' section is starting to go, and the whole thing looks a lash-up of Frankenstein's monster proportions and offends my OCD..
I'm going to buy a new down-pipe/flexi.. a new Cat on the mat.. and possibly a new lambada sensor so that everything down-wind of the manifold will be an MOT Tester's dream..
I have seen standard non-EE appoved cats (circa £50) and also EE approved cats (circa £70). My car doesn't need
an approved cat since it was invented when Zeppelins were still bothering Gravesend.. but EE approved cats are dearer because they have more Precious in them, isn't it? That means in theory they will clean up the exhaust more than a non-approved Cat.
Given that Blue always
flirts with Doctor Death, the emissions machine operator, at MOT time.. is there any mileage in getting an Approved cat,. for my non-approved cat requiring car...? i.e. Is Approved better/cleaner than a non-approved one?
Would my old beast be able to make use of the additional Precious in the cat (or would it make no difference without the necessary electronics etc. presumably that come with cars that need Approved cats?
