I got a call from FMF to tell me my header will be replaced free of charge. The weld at the collector had broken while riding in N Carolina a couple of weeks ago. I tried to email them and did not get a reply. Then I called and was told they wouldn't fix it. After posting this on Thumper I received a call from FMF saying it would be replaced. I believe it is the policy of FMF to stand behind their products 100%. I have also seen where one confused employee can screw up a companys reputation in a hurry. The power of forums such as these to inform fellow riders of problems with products we spend our money on is formidable. It is also important to identify companys that work hard to keep us happy. That is now my opinion of FMF.
