I have been referred to this thread and would like to give some information.
Ou Capristo exhaust bracket has the function to enable the exhaust to move
to the rear when being warm and to move to the front at cold condition. By means
of this exhaust bracket a lot of issues are avoided e.g. broken manifolds or broken
end tips. As a matter of fact the exhaust was firmly fixed to the gearbox previously
and now the exhaust is fixed to the chassis of the car. It is fixed to the traverse
where the bumper is also fixed too. The exhaust is lying on springs. Consequently
the vibrations caused by the exhaust should be absorbed by the springs. However,
if any vibrations are transferred and there are any components on the car (plates or
grilles) which are not completely fixed, then it could happen that these components
are made vibrating. One has to find those parts which are not completely fixed and
afterwards they have to be completely fixed. As a matter of fact with 1 or 2 of 10 sold
exhaust brackets our customers inform us about some vibration to be noticed.
However, after a throgough investigation, the reason for the vibration is found.
It is not the exhaust bracket itself, that is vibrating,but any other part of the vehicle.
However, a possible reason is that any part of the exhaust system has already any
kind of damage. I just try to imagine when the original manifolds have already cracked and the engine is being started, the exhaust would intend to expand , but
this is not possible because the original exhaust bracket is too riggid, the broken pipes get under pressure and, in consequence, they do not vibrate. Now at these
damaged manifolds the Capristo bracket is mounted. Our Capristo bracket allows the exhaust system to expand to the rear. Therefore the manifolds remain without any tension. And then the broken parts would vibrate as a consequence. This is
a theory of my own which is explaining to myself. In every case you should know that owing to the installation of the Capristo bracket your exhaust system is without any tensions and that will save a lot of issues in future. I hope that your manifolds
have not been impaired up to now so that they are already cracked. Perhaps you could try to put a piece of soft plastic between the mounting plate and the chassis
to isolate the exhaust a little bit from the chassis. It is all-important that all orignal Ferrari bracket parts are dismantled and that only the Capristo bracket remains on the car.
This is a short installation manual for the exhaust bracket so that you can see which OEM parts have to be removed. http://capristo.de/FTP/PDF/Ferrari-4...ng-holders.pdf
I hope that I could help you a little bit by means of this information.
