It has the m performance exhaust on it and after taking a look under the car i noticed a wire that is just tapped up and there is no electronic piece hooked to the exhaust. Which I'm guessing goes to the electric dump in the car.
I'm wondering if the dump isn't hooked up could this cause the plate inside the exhaust to rattle because it's not getting any power to the dump to hold it in place or could it actually be busted?
thanks for any help/pointers!

it's probably the exhaust flap/valve. i had the MPE on my m2 and they had a rattle issue that was fixed in a later revision. (they replaced mine completely, and the guy who owns it now had it replaced again, so it's on the third exhaust lol)
