Some of the cheaper decats have a smaller pipe than the exhaust you may be running so double check.

Most have an adapter for the sensor :thumbsup:

will the above link have the adapter?

or is this something i can just buy extra?

It has a lug for it but best ask them if its a direct replacement or not.

will do

its still safe to run one without the temp sensor though?

I think you will find its an O2 sensor but anyone please correct me if I am wrong :sadwavey:

Yep, it's definitely an O2 sensor. I know this as I had my MOT yesterday and there was a lot of discussion between the garage and me about it. Namely that the car still wouldn't pass the emissions, even with the CAT fitted.

Just a quick question about that: should the O2 sensor be 'before' or 'after' the filter that is contained within the CAT?

cheers guys

i have bought one with the 02 sensor

It's a cat temp sensor, not an o2 sensor. It is to warn of overheating the cat (useless or what?).

You don't need it in the decat pipe, I have mine tied up to the chassis. And it passed the MOT with the cat refitted but without the sensor refitted in the cat.
