As I am getting closer to my European Delivery, the brain starts working and I am considering exploring the mod area.

- full exhaust with no resonators maybe even muffler deletes (my favorite e39 m5 mod)
- or electronic exhaust cut out with the o2 simulator
- catless dowpipe
- tune
- meth injection
- upgraded intercoolers


Anyone explored the last 5? I am really curious and I am guessing people are too afraid of loosing their warranty, but it's worth asking.
