only one person has done that (Joepro). he's since sold the kit and not sure if he frequents the site anymore. I believe Sasha shipped the flanges lose and he had the crossover pipe cut and welded to fit. you are probably better off going back to stock headers. they flow well anyway and all of us are pushing stock block limits with them so unless you have a built motor you don't need extra hp
