I just wondered if this the case, because actually the Mp3 format is using a lot of of overdrives which is not possible in a WAV file. So if I e.g. make an audio CD with some Mp3's, will they remain exactly the same or will they differ from what an audio player would decode?

I think what the OP wanted to know was: If the MP3 decodes to something with higher-than-fullscale peak amplitudes, what happens?
Answer: If you decode straight into 16-bit PCM, anything beyond fullscale gets clipped. If you want to avoid that, you'll need a decoder with the necessary headroom and some additional processing to reduce levels before converting into 16-bit PCM (with dithering, yadda yadda) - exactly like a "proper" playback chain. How you achieve that is up to you. I might use Foobar2000's converter with Replaygain mode set to either "prevent clipping" or "apply gain, prevent clipping", assuming the files in question are RG scanned.
