Boxster catalytic converters - fix, replacement?

[redpepperracing]

blue62's idea is not new, it was tested by Project Farm:

This test demonstrated that not all penetrating oils are equal. Also, paying more doesn't result in better performance. In this showdown, ATF/Acetone mix, AeroKroil, Liquid Wrench, PB Blaster, Royal Purple and WD-40 are put to the test. Results: Liquid Wrench came out on top, following by ATF/Acetone, Royal Purple, WD-40, PB Blaster, and AeroKroil.

It was also the cheapest option, by far. Good luck, mine all broke instantly.

Nope.. not new at all it is what just about all shade tree mechanics used back in the 50's-60's.
You can mix the Acetone with Marvel Mystery oil and that works well also.
But I always have a little Trans. oil around so it is what I use.
Just put it on the rusty bits generously and often over a few day period.
The Acetone evaporates very quickly and it is what is taking the thinned Trans. oil down into the rust and threads.
So don't be afraid to use plenty. Also make sure you shake it well each time you use it.

Interesting, I've never heard about this. But I'm European, all cars are manual and no ATF sitting on the shelf, so it makes sense Always good to learn something new.

So, it seems like the aftermarket and used catalytic converters are in the same price range. Anyone with any experience/thoughts with either of these scenarios to share?

I see you, as I, reside in Cali. Might want to look into the newer rules regarding cat convs. If correctly I remember, they must have special stickers/registration/? on them. Almost registered equipment. i don't know the details... look it up. Good luck.
