    I must to replace my catalyic converter on my my 98 s70.
    Has small rust holes and it is throwing codes.
    Anyone have experence with aftermarket cats?
    I have heard good and bad and am looking for more info.
    If you have brand specific info please share.
    I would prefer to stay with original parts, but at
    just under US$1000 for the cat alone, I must investigate

    Also I have had a look at the coupler between the cat and the
    rest of the exhaust system to the rear. Mine is very rusted
    and I would like to replace both halfs. When I cuts the what
    I assume were bolts (now rusted to the point I can not tell if
    it was originnaly bolted ot riveted) is there a sealing ring
    or so called doughnut in there?

    All tips and suggestions welcome.

    Volvo warranty is 8 years, 80,000 miles on the cat.
    You are probably above the 80K miles.
    There is not a doughnut ring where the cat seals with the
    pipe. It is a flange seal that is made into the two pipes.
    A clamp goes aroung the two pipes to hold them in place.
    An after market cat will do just fine.
    Someone has got to make them.
