The general rule is if you change something like exhaust that part is no longer under BMW warranty. So if you go the a full exhaust then your exhaust and any problems from it (most likely none) will not be covered by BMW. A tune is a little different in my eyes b/c it affects the computer and if something goes wrong and your car locks up or an engine goes and they determine the cause was the tune (which they will) you are not covered at all by your warranty. This also goes for the supercharger. So basically if you change it then you are responsible for the issues from it. Just my .02.

Ps: so if you are wanting to keep your entire warranty then stick to BMW Performance parts.
