You have to master it .. I personally cap off all the niples and leave the exhaust port open ... fill to the top let it sit and expand.
You do have to do it a few times.
If your stinger is dented in .. run the car 1 tank so the pipe gets HOT and pull the stinger out VERY VERY CAREFULLY!
I have found a method that has been full proof in preventing the pipe from expanding out of shape and getting dents out that haven't crushed the cone or baffle, First put milk in the capped off pipe(all openings) then get a zip-lock freezer bag large enough to close with the pipe inside and fill the freezer bag 3/4 with water around the pipe and zip close then freeze,The water around the pipe freezes and prevent's the pipe from getting pregnant BAM! YOU HAVE HAVE IT, THAW IT OUT LIKE A STEAK AND CHECK IT OUT BRO,
