I just received this C63 (accepts quad exhaust tips) carbon fiber fin diffuser and it installed flawlessly. Paid $400 and had a little bit of an overseas wait time. I'm only accepting PICKUP at this point. I want to get a different version of the diffuser that I found after purchasing this one haha.

Price is $325 FIRM. Save yourself the hassle of a piece that may not fit correctly, and the shipping time.

Located an hour west if Philadelphia in zip code 18944.

let me know if you want to ship

 

From ebay. I forget the seller.
