Removing Pre-cats

[v8 mark]

I realise there have been other posts prior to this but once and for all.....
I want to remove pre-cats and possibly main cat, but leave lambda sensors in place...Will i still need a re-chip???? As the sensors are only after the pre-cats, sureley you can remove main cat, without any hassle anyway...So what do you think......
