300tdi need more power

<< < (4/4)

ross501:
i have taken the middle box out and its made quite a difference in power can i take the front box out aswel

Budgie:
If by the "front box" you mean the cat on the down pipe then it depends on the age of the vehicle and the MOT station you take it too.
I think that 95-96 TDi Discos can have their cats removed as there is no requirement for them to be fitted at that age. But, if your MOT man knows that it was fitted with a cat from the factory then he may fail it for not having one.  :wink:

Horness:
I've been running my 1998 TDi disco cat-less (with a defender downpipe, so no flexy bit to rot) for 4 years now, and it's gone through every MoT.

Next Friday it's off to Allisport for a full width intercooler, bigger rad and replacement header tank. Oh, and some tweaking.  :twisted:

Budgie:
Put a Defender down pipe on mine last week :wink: and I took the cat off about 4 years ago myself with no problems at MOT but I was just warning in case you get a "jobsworth".  :D
