This program claims to do it without decoding. Generally I thought this wasn't possible, or at least it's not to a sample level and thus generally not done. Maybe give it a go.

Or most audio editors will happily load an mp3, allow you to work on it and then save/export as mp3. Although it will be converted to a pcm file for working on this will be invisible to you as a user and hopefully any loss in audio quality will be minimal if you are using a high bit rate.
