Ven was replacing the headers in his Ferrari F430 but one of the header nuts was stuck. After trying many things, he resorted to using a Katana to bend the heat shield out of the way. Then he used a Dremel to cut the nut and finally an air-chisel to get the nut off. Quite the adventure. After all of that, the new IPE headers went in smoothly and now his car sounds great and he no longer has broken headers. During the test drive he did experience the slow down indicator plus his F1 system seemed to have some difficulty keeping up with fast shifting.
