My 89 325iX has some small holes forming in the catalytic converter and connection to the muffler, making nasty intermittent noises - mostly from the cat. Does anyone have a good used cat and/or muffler available? I see different part numbers for the cat on 325i vs 325iX - could a cat from a 325i work on the 325iX? The 325i cat seem to be easier to find used than the 325iX specific cat ... I've also gone to a few muffler shops and they would rather put new than fix. Does anyone know of a more flexible muffler place that WOULD try to fix this for me?
Any help would be appreciated.
