Hi, I just bought a used exhaust and I believe the previous owner had his car lowered causing the bottom end of the front of the tip to get scraped and it's got a pretty good size "chunk" missing. Is there anyway I can get it repaired? Is there a place that does this sort of repair? I"m located in the Bay Area, CA so if anyone can refer me to a place at or around here that would be great. Thanks in advance!
