Not today but yesterday I took the muffler off the hemi, opened it up and made a couple mods to it before welding it back up.
Sounds much better, deeper tone and slightly louder. It actually sounds like a v8 now! That said it could probably be louder tbh. Plans are to open it up again later on and completely gut it, replace the pipe with 3" perforated pipe and repack the muffler to make it a straight through. For an experiment however i'm pretty pleased with how it turned out, especially for free.
Stock the muffler seems relatively restrictive. For reference the circular and rectangular holes are ones i've cut. Also the outlet for the muffler chokes down to 2.5" ( inside the muffler )whilst the rest of the pipework is 2.75" Red lines indicate flow of stock muffler.
