As above, any feedback? Both are LTA approved. If the costs is similar for both, which one would you go with?
Feedback I received thus far:
M Performance
- Original BMW part
- Warranty provided by MA; supposedly will not void PML's side
- Nice M chrome pipe
- Minimal droning
Eisenmann Quad
- It is quad vs twin for MPE
- Better sound
- Void warranty but who cares
