That exhaust is going to sound great! I'm still undecided if I am going to upgrade mine, but the eisenmann is at the top of my list.
I just noticed you are over on M6 board as well. My username is "CatsFan".
Keeping with the black theme I would also do the side gills or whatever they are called in black and also pick up the color matched reflectors for the front which really helps to clean it up. Since my car is black I just wrapped mine in some gloss black vinyl I had in the garage, but getting rid of the orange really makes the headlamps pop.
