i have a wagner shorty header that has been rattling since about a month after i installed it. so i uninstalled it and checked everything, it looked ok, i retightened it and the rattle subsided. it came back a couple weeks later and it was worse. i took it apart again and noticed my gasket between the header and pre-cat was blown, so i removed it and just did without it. but the rattle was still there. so now i was thinking the pre-cat may be dead, so i asked nate0123, who is using the OBX header if i could steal his and the gasket. so today im taking everything apart to try the new gasket/pre-cat, and i see the welds around runner 4 are shot to s***. can i use JB Weld on this (never used it before) or do i have to send it back to andy?
