The setup you mentioned is a great design, although I would hold off on the Eisennman until last because the car does get significantly louder with Headers & high flow secondaries. In fact, every one of our customers who has gotten Header & 2nd cats combo eventually decided not to do aftermarket catback afterall. The general concensus seems to be just do headers & cats and leave the rest alone. After all the whole front section of the exhaust system is NOT AMG, its mercedes benz (manifolds, primary & secondary cats). Only the rear section is AMG, and they did a great job designing it. It is the front section that needs all the attention. (picture below for reference)

The AMG stock rear section (resonator & muffler) really is the perfect design for our cars so I would recommend waiting on the rear muffler until after the car has been driven on headers & cats for 1-2 months and the exhaust note has settled, then finally make your decision on catback. I have a feeling you won't get the rear muffler after all which will save you a substantial amount of money to spend elsewhere.

hope that helps,

(the top front section #5 #6, and middle rear section are the W208 AMG setup #13 #14)

awesome thx for that copy of exhaust diagram, all is clear now.
I'll go with your suggestion without the muffler initially, since that muffler is pricey. The tone the Eisennman gives from all the videos i viewed it sounds hard to pass. Headers + Cats would make it sound even better.

I just need to decide if i wanna go 300 cell or 200. I need to understand this raspyness you speak of :p
