PURPOSE: A structure for connecting an exhaust manifold and a warm up catalyst shell is provided to connect an exhaust manifold and warm up catalyst shell with welding work of just one time, and to prevent falling off of durability of the supporter by reducing the weld zone. CONSTITUTION: In the structure for connecting an exhaust manifold and a warm up catalyst shell, the bottom end of the exhaust manifold(10) is extended to be adhered on the catalyst carrier(14) surrounded with a shell(12) and a supporter(16), and at the same time the bottom exterior of the exhaust manifold forming right-angled adherence face(24) concavely is protruded toward outside to be curved. The upper end winded doubly of the shell is removed and made of straight adherence edge(20). Therefore the size of weld zone(28) made by the adhering of the adherence edge(20) of the shell and the adherence face of the exhaust manifold is reduced.
