It'll be fine as long as it's not smokey
Not when the temp guage hits half way, it's ok.
It's just when it's started from cold it's really smokey, nice clouds of black

Why would you decat a diesel. Must sound silly
Faster turbo spool up (makes a placebo like difference) and as Fonzee has said, lets it breathe a fair bit better.
I've got photos of my home made decat somewhere, the actual part I removed is v.restrictive, you looked down it and could see a 5pence pieced size of light
Janesy B.. how many times do I have to tell you that a 'Tractor' is pure porn

Decatting my diesel of doom adds about 6-8bhp, rolling road proven. Not done it myself!
Really? Most diesel CATs sit post turbo meaning the CAT would have no impact on the turbo spooling up.

Other than affecting the pressure differential across the turbine which is the primary cause of shaft torque to spin the compressor?

Yes.
You'd be suprised
My car only has one CAT, post turbo. Fitting a de-cat (and free flowing cat-back exhaust) dropped the boost threshold from nearly 4000rpm to about 3200rpm.
Placebo? It makes a massive difference :s

my rover 600 diesel sounds the same as before, the main reason for the decat is the turbo spins up faster and there is no turbo lag when you come back on the power after changing gear.
there is less back pressure on the turbo blades so it spins up quicker, simple as that and its not placebo
i had driven the car long enough with the cat to know the difference

What is the year the car was manufactured?
My friends petrol 1997 CTR went through an MOT with no cat. Clean running engine, but if the MOT guy had inspected the underside of the car thoroughly he should have noticed there was a bit of pipe where the cat should have been... and failed it.
