PROBLEM TO BE SOLVED: To provide an exhaust connection pipe capable of preventing fracture of a rendezvous pipe due to difference of thermal expansion between a shell and the rendezvous pipe. SOLUTION: In the exhaust connection pipe provided with a shell shape rendezvous pipe 1 including a plural pipe connection part 1a connecting a plurality of exhaust pipes and a single pipe connection part 1b connecting an exhaust pipe 1, and a shell 2 surrounding an outer circumference of the rendezvous pipe 1 with keeping a predetermined interval, the single pipe connection part side 1a of the rendezvous pipe 1 is formed with divided into two in an axial direction, an outward turn back part 13 is formed at one divided end part of the divided single pipe connection part, an inward turn back part 15 is formed at another divided end part of the divided single pipe connection part, and both of the divided single pipe connection parts are connected slidably in an axial direction by mutual insertion engagement of the outward turn back part 13 and the inward turn back part 15.
