On your Exhaust, question. I can say this only in the scope of my experience.
The high mount will indeed give you more bottom and midrange power without any significant loss of power up top. I ended up going with a full system with high mount and as much as I thought and felt the FM slip on I had was great looking, it seemed to give a bit of a hole in the midrange, and sounded like crap in my opinion.
I am going to be looking at adding a F3 675 for my Girlfriend to join the F3 800, and we will be adding a high mount on hers also.
As for the Dash, this might be a simple case of sodering new lights in the dash. I agree the orange color sucks.
