Except Weapons-Rice's copy-cat headers are thinner gauge then MSDS headers. Also with SS being more brittle that is a bad combination for overall longevity or for a turbo project like you mentioned.
I have had the MSDS headers for over 4 years and they've been partially wrapped (from collector's on) for over 2 years and they look as good now as the day I bought them. I am very happy with them.
