couple guys i know (audi/porsche mechanics) said that is really bad
i forgot the exact name of the stuff found there.. when i did it it was not much coming out, after every time i hit the chisel i let the dust settle a bit, and didn't breath while i was on top of it.

Interesting article. The metals used in cats (along with the exhaust crap they've accumulated)...
can't be good for you. Neither are the aromatics (toluene) that people routinely add to their tanks for increased octane.
I think it's important that we stress safety precautions of the mods we come up with on this group...especially as the group gets younger S4 owners (pre-owned) who are likely to look for easy/cheap power mods without looking at safety.

they are sitting in my basement ..are not in yet (maybe in the spring)
it took about 6-7 hours on Johnpa's car ..part of it friday and some left for sat.
without a lift ... big PITA.
i would do them in different days.. one day i would take out the front axle shields (right under the dp's = the hardest thing of all IMO) and move some of the driver side wiring out of the way, and the next day the dp swap.
see if you can get a car trailer (open middle) ..that would give a lot of space under the car

knocking the guts out is the easy part
On another car, "a guy I know", used a piece of concrete rebar he found in a dumpster. The rebar was used to hammer the converter guts into pieces. A coat hanger was used to yank the ball of wire support mesh out of the exhaust. The car only had one pre-cat O2 sensor so it wasn't vewry involved. The tough part on these cars would be figuring out where to relocate the sensor to, and having the threaded bung welded.
