Hey guys,

I've recently been struggling with an exhaust rattle caused by the center piece being loose. I'm stuck on how to fix it because the bolt doesn't fit with any tools and I'm honestly not sure what the function of this part of the exhaust even is.

Thanks!

That’s normal functionality of the part that is the exhaust flap. Leave it alone. They all make some noise. They make a little rattle all the way back to my 07 335 cars I had.

this is way old but if you haven't figured it out by now, there is a spring clip thats likely missing. Mine broke after 7 years. It's a thing that happens, 12 bucks at your dealership
