I have been told by Lotus that I need a new CAT for my 09 SC. The parts they have told me I need are:
Downpipe CAT assembly (part no: LB128S001F)
Exhaust O2 sensor (part no: LA117E6007F)
They are going charge me £1200 + labour to fix which is quite a bit.
Can someone offer me some advice on where I can get these without having to go through the dealer?

If your fairly practical you can fit them yourself (I did mine) or it's only a couple of hours work if you pay a local specialist to do it.
How come the dealer is saying it needs replacing anyway, has it failed mot?

I'd get a second opinion and test the o2 sensor and swap that out first if its faulty.
As above, how do they know its failed?

I did a Car Limits day and then a few days later I was just driving coming back from hampshire and lost power on the M40. I'd get jolts of power (like a belt was slipping or so i thought). If I accelerated slowly I'd get up to speed and just cruising was fine but if a put my foot down just a little, nothing, kind of like it was in limp mode but I would get some power if I did it slowly.
I took it to a local garage who I trust and he plugged into the ecu and there were warnings on the CAT. He said that if he were to guess it would be the CAT. I then took it to Lotus who confirmed it was.
I took it for its MOT last month and it only just passed.

Disconnect the pre cat sensor and see how it drives. When my o2 sensor failed it would throw all sorts of catalyst damage/efficiency error codes.
