I can say from owning an obx dowpipe on my volvo that i havent had any cracked welds or leaks in 4 years. HOWEVER, your headers will not be pretty for very long. my dp is about as ugly and discolored as pipes get. if u dont mind wht they look like then they will work fine. if u want people to go "badass headers!" when u op the hood, then dont get them.
