Akra slip-on or M Performance....can't decide....

Does the Akra slip-on drone at all? Also, does anyone know if the CF tips will discolor from the heat? I know that CF in the engine bay can turn a greenish-yellow from the heat. Definitely would not want this on my exhaust tips!!!

Anyone else cross-shop these? How did you decide? I have never heard either one in real life, and its doubtful I will ever have this opportunity. I have heard the OEM modded exhaust.
