Hi i've got a 1996 Discovery 300tdi with an exhaust blow from the flexi part on the front pipe.
I was looking at replacing it with a de-cat pipe but not sure how this will affect the mot.
Been looking online but getting very mixed answers.
If anyone can give me a definite answer if a de-cat pipe would be fine or if i should replace with a new cat please let me know, thanks.

Remove the above mentioned items, but do keep them safe, just in case in the future someone decides they must be fitted.

Cheers

If the mot guy notices the dpf (diesel particle filter) is missing and he's a jobs worth it will fail.done mine a few years ago no probs so far but still have it in my shed just in case.

Why worry about poisoning society if you get a tad more speed!

I may be wrong, but I think the 300Tdi engine did not have a DPF or even a cat. The flexible section is just that.
I also remember many threads about fitting a Defender 300Tdi exhaust which does not have the flexi section.
This is from memory when I had my own 300Tdi.
