    In this study, we investigated the reasons why exhaust manifold of a TC engine cracked in the durability test. We figured out the courses by quality inspection,CAE calculation, deducting and reasoning. After that, we optimized the exhaust manifold's structures aimed at the causes and proved ours thoughts by durability testing. This study is to suggest an idea about solving the similar problems for design engineers.
