Exhaust vibration absorber. The old one had come loose and was sliding back and forward on it's bolt. Left like that it would probably start acrack in the silencer, first reaction was take it off and forget it but then I thought it must have some positive function so a new one fitted.

Did you run at all without it? I am very curious how much effect it has and what are the side-effects of removing it 🧐

Sounds exactly the same. I have the feeling it's something that works in theory but doesn't have any real use in reality. But what would I know, just been a mechanic for most of my life, probably haven't a clue what I'm on about.:rolleyes:

No noticeable difference but I never had the chance to go over about 80 when it was off. It is marked 85 HZ, I don't know what sort of RPM that comes at. mine being an auto the revs are always fairly low when cruising.

85Hz is equivalent to 5100rpm, but not sure how relevant that is to the exhaust. Probably needed to deal with some sort of resonance in certain circumstances.

It would be interesting to take it off and run at 5100 RPM and see what the difference is. I normally only go over 5000 for a few seconds accelerating.

They certainly stop resonance in newer bmw and jags etc when you look at them at idle exhaust quite still and they vibrate if hold it still that resonance transferred to the exhaust so still used today so definitely more than snake oil when it makes much difference not being there on a 25 yr old z3 is another thing altogether.
