400 was stainless steel. 430 is just mild steel.

Being mild steel it will eventually fail at some point

The Headers are stainless as are the primary CATs.
Y-pipe is regular steel wrapped in fibre and an aluminium cover.
Not sure about the section that connects the Y-pipe to the resonators or the resonators themselves.
The final silencer sections are regular steel but seem to last pretty well.
My 2004 has 130k miles and has had to have the Y-pipe replaced due to cracks where the tube was welded to the flange (cost £150).
Otherwise the resonators and silencers look good with no visible rust or cracking on them or on the tubes linking them.
