Not sure if this has been posted up before, but here is a company that makes a custom full exhaust system for Subaru Sambar. Sorry that the page is all in Japanese, but if you click on each pic you will get an enlarged photo, also the pics below will show pricing when clicked on. If anyone needs help with translating Ill be happy to assist, just let me know. There is a video at the bottom of the page where you can hear how the system sounds. FYI currently 1USD = 96JPY. http://www.metalspeed.co.jp/car_samber_index.html
