Demon Tweeks or a certain online auction website would be my first port of call, followed by companies which manufacture custom exhausts.

Definately try a custom exhaust manufacturer,depending on how the cat is fitted in the system it could as easy as cutting the cat out and replacing it with a straight piece of pipe.

I cut the CAT open and knocked out the ceramic core. TIG welded it back together so impossible to tell it has been decatted.

Was looking there at the CAT...


So if u cut the ends off there does the direct heat off the turbo not break the welds??

Heat won't break the welds. Looks like you can knock out the CAT without opening out. Perhaps you can reach inside using a suitably bent round bar.

It's not a Cat on a diesel, it's a partical filter, and it's unlikely to pass an MOT without it.

With a petrol engine a healthy engine and fuel injection system often will pass an MOT without the Cat, and a Cat is not a legal requirement, the only requirement is that the emissions test is passed.

I'm pretty sure there is no sensor to detect a faulty Cat (partical filter) on the diesels.

Why don't they do smoke tests?

Thats happydays then!! Ill have2 book it in wit an exhaust specialist!


Not sure y in Northern Ireland they dont. The only thing remotely like it they do would be sometimes rev the engine hard 2 see if it buckets out black smoke...

I had tdi bora and got £46 for the CAT in it at scrap metal man? So is that not just same as petrol 1's then? Same materials...

i'm pretty sure the internals are a different material, as it's a soot filter, whereas the petrol cat is designed to change the gasses

Took underneth protective panel off there for a look...

Did u find it hard to get CAT out past driveshaft?? Its looking a bit hassle! :crazy:

There's 3 bolts at turbo then 2 bolts at exhaust and finally 3 bolts from the CAT frame to the box...?

Mine is a Kangoo Trekka 1.9 Dci from 2002. Easy access. No particulate filter or other complications.

did this happen with u??
the truthful answer is not yet.

in the not so near future, im going to have my car chipped (who can say no to 170bhp) and whilst they're at it they are going to remove the fap (which will give me another couple of bhp), and to do so they have to trick the ecu into thinking its a non fap model of car.

I'm pretty sure the older ones wouldn't know it was missing, I'm sure there is no sensor for it?

of course there is, otherwise how would it know when it needs regenerating?

So in conclusion lol!

its not worth the hassle getting some exhaust specialist 2 cut wat ever the hell the thing is ''CAT'' ''particle filter'' or what ever as its going 2 put the service light on in car and have2 get it re-mapped 2 take it off?...
