Got a crack oem 04 sti headers by uppipe (one of the pipe) and was wondering if it is weldable? On a budget and if they can be than I might go get it welded instead.
Its a special process to weld cast. It can be done. That is the same manifold as just about any other turbo Subaru. up to 2013 I think. I know my 02 WRX and 05 LGT had the exact same header/mani.
