Question Exhaust Experts...what is this unit?

I am almost done swapping my exhaust with a factory Nismo exhaust. Now if you are under the car, on each side past the brass-looking net/mesh, there are black rubbery units that are bolted to the exhaust. They don't have electrical connections.

Are these dampers? Are they needed?

Thanks.

They are there in order to dampen and remove any resonance in the exhaust pipe to relieve any potential vibration. Basically, I think it is overengineered and unnecessary but it is a vibration/resonance damper.

Than you Sir! I have managed to transfer the units. I figured no "harm no foul".
