I'm building a Aurora 60 that I purchase from Don at RCAir. I have a NOS OS 61RF pump that I will be using. I am looking for a Hatori 730 header pipe(new or used.) Also, can anyone tell me the correct muffler to use with this setup? From what I have read so far, it will be either a Hatori or a Macs, but I don't know what # on either.

Thanks, Ken
