No cats

Yes it will (make more noise that is)
Quite a lot of people just hollow out the cat.

Quite a lot of people are ILEGALLY hollowing out or removing the Catalytic Converter. It is a violation of federal law to muck with a REQUIRED air quality componant. The EPA mandates CC's otherwise the manufactures wouldn't put em on. You gut the cat, you don't have a legal vehicle.

Its only gonna get worse. In 07 you'll see NOx scrubbers as well.

It has a mesh material inside. My advice would be to buy an exhaust system which leaves the converter, then buy a converter test pipe that will bolt in place. That way, if you need the converter back in for some sort of inspection or warranty work, it will bolt back in.
