Allpar Mod Posted July 5, 2010 Share Posted July 5, 2010 I have to replace the rear cat on my '99 OBW. So far, for an exact OEM style replacement, the best price I can find is from autopartswarehouse.com, $146 & change. If I want to go through the hassle of a universal, I can get one for $77. Anyone know of any better prices out there or possibly have one laying around? The rear cat on this model houses the downstream O2 sensor.

Steves72 Posted July 5, 2010 Share Posted July 5, 2010 When you talk about catalytic converters you get what you pay for. A universal cheap cat is not going to have very much of the precious metals needed to clean the exhaust gasses properly. Nor, will the cheap OE fit units. Ask a mechanic, any mechanic, the brand they use as a replacement cat. They do not use the cheap units because they do not want the job to come back to the shop. You may not even get the service light out with a cheap cat. Steve Quote Link to comment Share on other sites More sharing options...
idosubaru Posted July 5, 2010 Share Posted July 5, 2010 I bought a cheap one last summer for a friends legacy and it's unbelievably rusted after only one year. Doesn't look any different than the original stuff that's still on there. This is tough spot for older subaru's. cheap stuff doesn't last but the high price from Subaru is a tough bullet to bite too. an exhaust shop that will weld in new pipe for $50-$100.

That will not fly if he must pass an emissions inspection. Steve Quote Link to comment Share on other sites More sharing options...
idosubaru Posted July 5, 2010 Share Posted July 5, 2010 copy that, i was thinking rear pipe. i bought a $80 cat off ebay last year for a 97 legacy, brand new, and that's what's rusted really bad. it's still working and hasn't fallen apart yet but man did it rust quick.

GeneralDisorder Posted July 5, 2010 Share Posted July 5, 2010 Many people have bought the cheap cat's - only to find they don't work well enough and they end up with P0420 codes indicating catalyst inneficiency. Gut the old one or if it's too rusted up have a straight section of pipe installed then space the rear O2 sensor away from the exhaust stream with a non-fouler to eliminate the code. Cost is about $8 for the non-fouler(s) and whatever solution you come up with for the cat or pipe section to replace the cat. I've "fixed" many catalytic converter codes on many different cars and trucks this way. Usually for less than $200 including my labor charges.
