2014 F06 Gran Coupe Noise

Ok I've got two things to bring up:

1. After installing BMS charge pipes and intakes, the car has some kind of fluttering noise under WOT. It doesn't seem to impact power, but I'm hearing almost like a repeated chirping. Could be turbos, but my N54 turbos never sounded like that.

2. Am I nuts or is it impossible to find front sway bushings? I have some popping up front, so I replaced the sway links. I'm still hearing/feeling the popping while backing up and turning, so I thought I'd go to the next step and replace the front sway bushings.

Guess they're built into the sway bar assembly or something and I'll just have to install a full upgrade if I want to go that route. Closest I found was here, and they're probably for the regular 6 series:

Thanks for any input

Maybe check all the seals around the charge pipes and air intakes. I have had issues with them not getting sealed well on the under/back side of the hose. With the charge pipes have had them break their seal a couple of time after a short spirited period of driving.

When I had the popping issue it turned out to be the sway bar end links. I may look at doing the sway bar bushings soon as I am sure they are nearing end of life.
