OK guys I have been talking to Some people and I just want to let you know That F.I. Inc. will be looking and making HFC's, test pipes and a cat back for the FX50S. Maybe even long tube headers. If all goes to plan the fab work should be started this December. I have this make of exhaust on my G37 and know a few 370Z guys that have this and love it. They are making long tube headrers right now for the G and Z and hope to start the exhaust for the FX soon. Lets keep our fingers crossed.
