Gina, I've got pipes from chevy605 (on this forum) that are not EFI pipes, on my EFI '09. The are a bit louder than TORs, but not obnoxious. And they do not need re-mapping. The shipping would be a lot, but you might want to contact him and see what he does to them, then have someone local do the same.
The sound reminds me of the '69 Bonnie I had way back when, but I thought that might be just me and a faulty memory (age!) but I met a local rider with a '67 and the bikes sound very similar.
Just a thought.
