Whilst changing all the fluids on the p38 at the weekend I happened to notice the exhaust system seems to be on it's last legs. The back boxes are seriously corroded, the centre box isn't much better and the bracket that supports the exhaust by the catalytic converter is hanging on by a thread.
I'm presuming whats under there is the original exhaust as the vehicle is just coming up to it's 10th Birthday and I can't imagine its the second system about to give up.
Couple of things, Firstly can you do away with the catalytic converters on the P38 Diesel?
Secondly, has anybody recently done this exercise (replacing the exhaust that is) and weighed up the cost of either fitting a stainless steel system, a genuine Land rover system or a pattern part?
In my previous experience pattern parts don't always fit that well. I figure if I'm going to go to all the expense of buying a new exhaust I would rather have one that fits properly. I cant see any point having all this luxury if all you can hear is a poor fitting exhaust banging around underneath.
Trouble is I have already spent a monumental amount of money on this vehicle over the last couple of months so I need to be a little careful as to which route I take with this.

Any suggestions or previous experiences greatly received,

Dave

Your diesel does not have a catalytic convertor it has a particle filter. It collects soot particles at low rpm or when the engine is running cold before it reaches operating temp. It then heats up and burns them off when running at speeds above 40 mph. There is nothing in the current MOT that covers them as far as i am aware. If you get a pattern exhaust made by Bosal it will be just as good as the Landrover part. They make the genuine ones also.

as for removing cat/particulate filter but for ease we will call it a cat!
i removed it on my previous dse and welded a straight bit of pipe in its place no one makes an off the shelf decat pipe.
i will be removing the cat on my current dse when time permits as i think there is a difference in how it picks up and performs.
this time around iam going to look into an easy way off doing it without involving welding as it is a pain to remove the downpipe to do. should be a case of cutting it out and a link pipe that will clamp into place.
on an old rover L series diesel that i tuned saw a 7hp increase on a rolling road so where poss i always remove them!

Is it possible that the vehicle has a particle filter and a catalytic converter?
I had to take my wife's cars in for tyres today and whilst talking to the garage owner he opened by his exhaust book and we had a quick look.
I said to him about your comment Wammer but he reckons its definately got a cat not a particle filter. When I enquired as to how much to replace the whole system excluding the manifold he quoted me £665 + vat, I nearly soiled myself.
Any further input on this matter would be greatly received. Its a 2002 vehicle if it makes any difference.

Yes it would seem i was incorrect about particle filter and it does indeed have a two way cat. In which case the new MOT regulations state that it is a fail, if a cat is not present when one was fitted as standard. Sorry for the misinformation.
