Bellowed up pipes have a flexible section of pipe so that the pipes can move/expand with heat. They allow for a better seal because both ends of the pipe are bolted down solid. The stock setup uses a gasket at the collector end that wears out in time, and can wear out the up pipe to the point that a new gasket will not seal and you'll still have a leak.

International. Some have had very bad luck with aftermarket. Typically aftermarket have quality-control issues....so if you want to roll the dice, go for it.
