Abstract: The present invention relates to a connecting structure to connect a warming-up catalytic converter (WCC) and an exhaust pipe with each other. The connecting structure of the exhaust pipe comprises: a WCC having a first flange formed at an end thereof, the first flange having a first bolt hole; an exhaust pipe having a second flange formed at an end thereof in such a way as to come into contact with the first flange, the second flange having a second bolt hole; a guide bracket of which both ends are bent and of which one side presses the first flange and the other side presses the second flange when the first and second flanges come into contact with each other; and fixing bolts respectively inserted into the first bolt hole and the second bolt hole to fix the first flange and the second flange. Compared with the conventional stud structure, the connecting structure according to the present invention is enhanced in assemblability so as to enhance productivity and does not need bellows. The connecting structure has a supporting part to put the second flange thereon in such a way that the first bolt hole and the second bolt hole are opened, and a user can easily insert the fixing bolts into the bolt holes.
