:shock:
Aloha! Anyone noticed a difference with their Tdi s after removing the cat? :roll:

davidlandy:
yep i did on my defender 300tdi - much better low down pull it seemed.

and makes no difference for MOT - go for it

remove EGR too.

bilge rat:
yeah , slightly better, did take off the egr valve too and tweek the pump. defiatly makes them more drivable (no flat spot at bottom end) . alan.....

bilge rat:
no difference in fuell consumption really either . alan.....

Disco Matt:
You can buy a stainless pipe to replace the centre silencer (presumably the cat is in there?). Judging by how mine behaves after I fitted a stainless exhaust which only has the back box this is well worth doing!
