Gutting pre-cats may not prevent engine failures

[SteveJ]

'53 plate 18k miles - left hand precat was showing serious signs of degradation so I dont think the pre-cats have been redesigned (or if they have it hasnt done the trick)

Car continued to 39K before I sold it without any problems (except BIG lumps of the LH precat missing by that point), but I did stay away from 4K rpm
