SUNRISE, FLORIDA -- For a Christmas present I ordered a header for my son's Honda Civic. I received the order, correctly, in about 10 days. When installed it was discovered there was a small hole in one of the header tubes - obviously a manufacturing defect. When I called and actually got to speak with someone I was told they would ship a replacement - never arrived. Called again, got switched to someone in shipping who would take care of it and give me a call back. No call, no product. Sent an email no response. Called again customer service representative fuddled around trying to figure out who they got it from and said they would ship a replacement and let me know. Again, no call, no replacement. I called them back and was told had shipped. After two weeks called another time representative supposedly IM'd manufacturer who said they would ship a replacement and email a RA. Again nothing.
Do what you feel is best for you but don't expect any service.
