Removing W900L muffler

I would like to eliminate reverse flow muffler. Would like to put one inline next to tranny then 45deg bend and dump into Y pipe after flipping it around to the front. Does anyone know which muffler fits? Have heard of this being done but haven't found out which muffler to use. Prefer not to straight pipe, have PP muffler under bunk and she barks pretty good already. Thank you to anyone who can help.
