It has been a couple of months sense my exhaust install and at least once a week there was a flap noise coming from the trunk but could not be heard outside the car. Like a rice can exhaust noise. I gutted my rear interior for some track time and I found what was making all the noise. The two vents in the rear of the trunk were viberating due to the tone of the exhaust. Sorry of the crappy video but hear is the noise. Much louder with no interior.

Thought maybe some others have heard this in their set ups as well. I made a small adjustment with some padding on the small flaps and now the sound inside the car is so much better!

PS: Yes the airbag light is on due to the rear seat center belt tensioner being removed.
