Please help! Searching: a very small muffler with abe.

Hey there I’m currently working on my Honda build and I’m looking for an very small muffler to fit underneath the bike. It be great if the muffler had an abe (German thing that says the muffler is allowed on the street). But first priority is that the muffler is small. If you know any companies that make small mufflers please let me know. Thanks for the help, Erik via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/9w5gyt/please_help_searching_a_very_small_muffler_with/?utm_source=ifttt
