No mods you do will void the warranty on your car...
But, if something goes wrong and the modification is directly the cause then it will be an issue...
if you have a problem with the emissions system (O2 Sensors, etc) then it will not be covered under warranty if high flow cats are installed...
if your aftermarket parts fail, they will not be covered under warranty from the dealer...

As was said, no mod will completely void your warranty. A dealer may refuse to work on your car based on a modification, but they cannot void your warranty.
On the other hand, if the cat convertor plugs, overheats, causes a huge exhaust restriction, causing really extreme exhaust temps and damages the engine, repairing the engine is probably not going to be covered by warranty since it was an aftermarket part that caused the failure.

Spend a few minutes and research the "Magnusson-Moss Act". This act protects car owners by allowing the use of replacement, non-OEM parts without fear of voiding a warranty that covers remaining OEM parts. As stated however, if the aftermarket part causes damage to, or the malfunction of an OEM part or system, you are on your own (unless you can find a mod-friendly dealership.)
Also, one note to at least be aware of: It is a violation of Federal Law to replace, remove, or modify a working OEM catalytic converter. (not that it stops anyone, including me).
Here is an entry from the page linked at the bottom of this post:
(6) When can I install an aftermarket converter?
Generally, there are only 3 situations when you can install an aftermarket converter.
They are:
(1) if the converter is missing from the vehicle when brought in for exhaust system repair; or
(2) if a State or local inspection program has determined the existing converter has been lead poisoned, damaged, or otherwise needs replacement; or
(3) if the vehicle is more than 5 years old or has more than 50,000 miles* (8 years/80,000 miles for 1995 and newer vehicles) and a legitimate need for replacement has been established and appropriately documented (e.g., a plugged converter or unrepairable exhaust leaks).
Any other converter replacement must be with a 'certified' or new original equipment (OE) or equivalent converter.
Aftermarket converters subject to the enforcement policy requirements cannot be used for replacement if:
(1) the existing converter is present and functioning properly; or
(2) the replacement is under recall or warranty; or
(3) the vehicle is returning from overseas use.
