Anyone know if I remove the catalytic converter from my 2005 TD5 Disco
if it'll make any difference? I assume the engine will be able to
breath easier, and Rimmers list 2 downpipes, 1 with cat, 1 without. I
also presume the MOT smoke test is essentially that, a smoke test with
a probe up the tail pipe, and no check for what the cat should have
removed, unlike a petrol MOT test?

AFAIK this is the case. Did it with an M-reg 300 TDi.

replacement to boot out the cat. ?

We're talking TD5 here - does it have a cat? Is Rimmers list for the 300
TDi Disco 1?
