while the dust is an irritant and is to avoided, i have never seen any evidence of the cat materials themselves being cancer causing. sure, lots of rumors and urban legend, but no MSDS docs or the like. afaik, the priciple catalysts are platinum and palladium, both fairly innocuous metals. the substrates are also inert from what i've read.
again, don't breathe the dust, which is pretty much true for ALL dust. i found a small water sprayer very handy to keep it down.

Check out the S-Squared Motorsports uppipe. It's high quality, with a flex joint and an EGT/02 sensor bung, and generally sells for $225.

just popping in to say that i'm sure most uppipes probably have different airflow characteristics depending on teh diameter, and the heat-absorbtion characteristics of the type of metal used while at operating temperature, but i think for the most part the gains are negligible between most pipes. The major benefit is just in getting rid of that super restrictive 1st catalytic converter. One other thing to consider is the type of metal used for the pipe, some i think are made out of cast-iron or steel like the stock pipes (not sure which), while many aftermarket pipes are different grades of stainless. I like the idea of stainless just so it doesn't rust.
also, the flex idea sounds like a good idea but usually ends up being a bit more expensive. I've had a catless non-flex pipe (PDE)for ~50k miles and have had no leaks or fitment issues. Flex is probably a good idea, but probably a little overkill unless your car sees some serious tweaks and bends like a rally-x car probably would.
just my 2 cents...

I don't think that a flex pipe is really required, or most of these companies would probably be out of business. I think you'll be fine w/out a flex pipe. I'd recommend PDE, Perrin, or Vishnu as far as non-flex pipes go. I have never heard of any fitment issues with any of those companies. i've got a PDE and it's awesome.

How is the flexpipe easier to install?
Any new uppipe is pretty easy to put in, really, the only pain in the *** part about the install was getting the stock pipe out... then getting all the turbo heatshields back on.
I guess it would help while trying to get all the bolts and what-not aligned?

I just bought a stainless steel up-pipe from Gruppe-S. When I asked about this 2 months ago, ppl said there really wasn't a huge difference between the flex vs non-flex. I haven't installed it nor do I know the pipe diameter, but is was cheap at $175 incl gaskets.
