I fixed my floppy crossover for good . The front crossover on 03 and 04 V11’s relies on a graphite gasket to seal between the crossovers ball end and a standard exhaust tube. Invariably, the gasket takes a set and the crossover becomes loose and can not be tightened enough to compensate.   I had some stainless steel shims turned that mate with the ball at their inside corners. The shims still allow for the ball joint to swivel until installation is complete and the clamps are tightened. Once
