Look for the user QxR in 1337x. They include extras in almost every release, I believe.
If you are only interested in the extras, you can tell your torrent client what to download. In qBittorrent you go to "Content" in the lower part of the screen, and mark what you want or not. In Transmission go to Properties>Files. I'm sure that in most clients it would be a very similar process, but those two are the ones I'm familiar with.
