I can’t find the thread where the merits of removing the rear exhaust brackets (I think?) on a F430 were discussed as a solution to the header problem. As I remember it, the argument was that these rigid mounts caused twisting of the headers/manifold, and for the manifolds to fail. Sorry if I have some of the technical terms wrong. One solution (apart from getting a new exhaust system) was to remove the rear brackets on the back boxes, I think.However I can’t find this thread. My car is going in for its annual today, and with a new lock down and dealer closure announced in the UK from later this week, I am now in a hurry to make sure they get it done this time, rather than me having to go in again just for this issue next year (the dealer is not close to me). Help much appreciated!
