I'm going to replace my SB headers, and am debating whether to buy the $100 summits and get them coated by QC, or spend $280 on flowtechs that are already coated. my non coated (just painted with eastwood stainless steel paint) have surface rust, but have survived suprisingly good over the past 6 years (with 2 1/2 years of year round driving here in west MI. if I spend more than twice as much to get coated headers, I want them to last twice as long. one benefit to coating is I can weld in O2 bungs and put any clearance dings in I might need before coating.....
