It is there to test the resolve of any owner who attempts to work on their Cerb themselves!
Jokes aside, I have been told (by those who should know), that it doesn’t really serve much purpose, although there are no hangers for the exhaust mid-pipes and this plate does (by means of a rubber bung/grommet) support the exhaust pipes, at the point where the welded tabs come together - the tabs often break off, and the rubber bung often melts. Depending upon the exact geometry of the pipes on any particular car, the aforementioned plate is affixed at a distance from the chassis, by means of multiple washers and a couple of bushings - all of this adds to the Meccano feel ;-)
It’s a pain in the ass, but looks (somewhat) cool.
Just avoid cross threading one of those bolts with a high power impact gun...

The alloy version that I've made cuts the weight in half but retains the strength by being thicker, new spacers (not washers) make it easier to get up
My own car never had the mid point mounts for the exhaust so fabricated my own and has certainly helped reduce the movement of the exhaust.

Really , who are those people ?
It’s an opinion, not sure it matters who it came from, we can take it or leave it.The bolt holes in the plate are larger than the bolts, and the plate itself is not particularly rigid, so I don’t believe it can add much rigidity to the chassis, the tolerances just aren’t there.
If it’s sole purpose is to support the exhaust pipes, well it only does that at the very back, so a much simpler bracket would have been both lighter and cheaper as well as being much easier to remove and reinstall.
I don’t know of any other cars that have an assembly in place to catch a failed part of the exhaust assembly, so to my somewhat inexperienced self, the notion that it didn’t serve much purpose seemed logical.
But, I’m always keen to learn, so if someone knows the real and maybe higher purpose of this part, then I’m with Mr Cerbera and I’d love to hear it too!
Thanks

It matters because you say "people who should know" and if you are acting on that fact and significantly weakening your chassis .
Yes, I see your point.It matters because you say "people who should know" and if you are acting on that fact and significantly weakening your chassis .
I must admit, I was working on the premise that the chassis is made of large tubular sections with significant cross-bracing on the 3 out of 4 sides. Any flexing of the chassis would be a result of very significant twist force (high speed cornering), but that such significant force would far exceed the lateral support provided by the chassis plate, not least because the bolt holes have a large tolerance.
Even though I’ve taken the dam thing off and put it back at least 10 times, perhaps I’m miss-remembering the tolerance of those holes.
I will take a look...

Hi David It matters because you say "people who should know" and if you are acting on that fact and significantly weakening your chassis .
As the subject title ays, I am always interested in Cerbera owner's thoughts.
We are an interesting and creative group with strong, decisive minds.
I don't have the tendency to suicide so all comments are welcome..

Sounds like titanium replacements would make a big weight saving.
I have replaced about 70% of the bolts on my car with Titanium.
People spend 4000 plus on 20-30 bhp but they don't like to spend money reducing weight which improves many more areas of performance. My battery was £600 and saved over 15kg

Yep, best leave all this sillyness to folks who have more money than sense.
Pass the port!
