Default Check Engine Light, P430 Code and Car cutting out at full throttle

Ive been having this problem recently with my WS6. First I noticed that the SES light came on out of no where on day. So I went and got the car scanned today and it was throwing the code P430. But last night before I got it scanned and the SES light came on I noticed that the car under full throttle cuts out really bad and its very noticeable. Almost like somthings holding it back and restricting it. I also noticed a loud humming sound coming from the exhaust and it gets louder everytime I drive it. Its not like a rear end whine its a humming noise.

Heres a video of the noise from inside the car.
