Its the front section after the manifold including the centre cat box. The car still has the factory piece on except the scorpion half system ( Back box and pipes leading to centre box) Which i put on last year. I can get the part from bmw although very expensive!, but euro car parts say the part i need is a manufacturer only part after they sent me the one for my reg number but it was totally wrong
The part has the lamda probe on the down pipes just after the manifold and the cat in the centre box.
The car is a 1992 j reg 325 cabriolet on a private reg J2HRK origianal reg J548SPE
