Oh, sure, get all artsy and designer layout on everybody.......
Zat paint or powdercoat on them there items?
If it does turn out to be the exhaust hanger, you can indeed do without it, but you'll wanna check the joints at the center muffler and manifold periodically to make sure they're staying tight and sealed.
It's absence will also put a bit more stress on the manifold proper.
Instead of the exhaust turning/twisting with the engine and trans under torque when the bracket is there, the exhaust will actually fight the torque a bit and that stress ends up at the manifold.
This can result in frequently loose manifold nuts at the head, and worst case scenario, that sexy crack that the S3 manifolds sometimes get.
Not trying to throw a scare or anything, just trying to impart that there's potential issues that could arise in it's absence over the long term.
