i use channel lock pliers to snug mine on and snug it off. try heating it up maybe someone put loctite on it ? liquid wrench or penetrating oil? also that tab on side stay still and just the cap un twists
Yeah id order a new flange also but fmf flanges dont come with the o-ring style seal..only ones I know of is the toomey and im guessing dmc alien cause there leak proof also.. fmf trinity ct all have sh*tty header to flange connections!! I never understood why they all dont make pipes so there nice and tight and not blow sh*t all over our bikes unless we seal them ourselves
I found a stock one with a tors eliminator kit and idle screw installed newly rebuilt. SO im going to get that. I let it sit in wd40 over night put it in a vice and it still didn't come apart lol
