Id even go as far as to say some of the stock fx400 headpipes would perform better than the HMF's headpipe. I dont really understand why there is such an inconsistancy in the welding setups. Of course these parts are assembled by hand and not robot so human error has a lot to do with it. Just like the collar welds . Some are smooth and tight to the pipe and some are huge tall restrictors that need lots of grinding .
