I KINDA FELT THEY WERE WHEN I SAW THEM. If and when I get them out can I replace them? can I drill more holes and re-wrap them in fiberglass(if it is ifberglass) im still waiting on someone to tell me what the material is. It sure looks like fiberglass. If I cant get them out I guess Ebay they'll go and merry Xmas for me! SANTAS BRINGING NEW HEADERS(CERAMIC COATED)
