:) Hi Folks

Wallbanger hear

Hears a question for those who know. Catalitic exhaust thing;y majig;ys, I;ve just been told that a cat in your exhaust on a deisel is a waste of time as it dos;nt do anything like it does on a petrol engine. Its also been suggested that it slows the engines acceleration becouse the exhaust gases are held up by the cat.

Bottom line:
I've got a 300tdi discovery
1. Have I got a cat. :confused:
2. Do I need a cat.:rolleyes:
3. Will not having a cat inprove performance (of the car that is).:D
4. Will getting rid of this cat effect the MOT.:eek:
And finaly
5. If I,ve got one and dont need one whats the cheepest way of getting rid of it.
P.S. wheres the bl.......dy spell checker on this thing!!!!!!

Possibly - depends which year, easiest way is to get underneath and have a look!
2. Do I need a cat.:rolleyes:
No
3. Will not having a cat inprove performance (of the car that is).:D
Yes, a little
4. Will getting rid of this cat effect the MOT.:eek:
No - not required / tested on doozels
And finaly
5. If I,ve got one and dont need one whats the cheepest way of getting rid of it.
cut it out and weld in a straight section of pipe in its place!
P.S. wheres the bl.......dy spell checker on this thing!!!!!!

yes, performance and mpg wise, the cat is a waste of time..

i too would also like to know, if it is removed from say a 94 t0 96 tdi, will it have to be put back on for the mot ????
 
not required on doozels... i see...

i had a feeling it was on petrol..

not so on diesels you say??
 
Bl...dy hell folks that was quick are you all sitting there bored with the crap on tv like me ?
its looking good so far.
If I get rid of my cat and my EGR thing and fit a chip, and fit a carlos fandango air filter the old beast should in future do 0 to 60 in only 5 minutes. Great improvment.
Do you think Land Rover should give us all a rebat on the bits we dont need?,
And is there any think else I can get rid of, just loosing the waight,s got to be a benefit.
 
don't bother with a boy-racer air filter - they're just for posers and may well lead to premature engine wear.
egr blanking is first priority.
 
right okay thanks so I wonder why the fuel enconmy is lower on 200tdi then 300tdi ??? I do about 30 miles to a gallon at max of 60 mph and never revs higher then 3000rpm.
