All pre 2002 Disco td5s came from the factory without a cat. Its purely an emissions device and has no other effect on the car. There are endless posts on de catting the td5 and all the mot discussions.
By now, most Td5 cats will have broken and burned up and likely have limited effect on emissions.

Back pressure is never a good thing despite what all the tossers down the pub spout. How could it be?

It is very good with 2 strokes. And get the resonance going it really boosts the power.
I got roughly 3bhp from a bike with a bit of porting and an expansion pipe, was 100cc but I could beat quick 125s

When I did mine, I never had to get any cross member off. but then all I did was replace the middle box with straight pipe as I had no cat, so maybe we is talkin at cross porpoises!
