Hi all, iv bought a replacement exhaust and there is no hole in the new exhaust for an O2 sensor after the catalytic converter. The original has one. Does anyone know is it needed for fueling, or is it just to report on the efficiency of the cat?

Cheers,

Laurence

No joy with getting to the bottom of this with part numbers. It was a mail order job and a faf to send back.

I picked up a weld on O2 sensor collar for a couple of quid. Will take it to an exhaust shop and have it installed the same distance from the cat. Fingers crossed
