I'm glad these posts got started on FMF. Yes, I think their products work most of the time BUT their customer service S%&^Ks!. I wanted a simple answer about header pipe application on a 4 stroke (Power Bomb vs Hi-Flo) since they have conflicting info on their website, claiming in differing pages that first one, then the other is better for a particular rpm range. I have e-mailed their "tech" dept 4 times: no answer. Now I'm just going to send the same e-mail over and over every week until I get an answer, but mostly to annoy them: I just don't care anymore about their product.
No tech/customer support = I buy from someone else. Plenty of choices there.:mad:
