Abstract: An exhaust system and a method of joining components of an exhaust system comprises obtaining an outer sleeve, a first pipe with a first end, and a second pipe with a second end. The method includes inserting the first end of the first pipe within the outer sleeve to define a first overlap, inserting the second end of the second pipe within the outer sleeve to define a second overlap, and radially inwardly deforming the outer sleeve and the first pipe at the first overlap. The outer sleeve and the second pipe are radially inwardly deformed at the second overlap. The outer sleeve and the first pipe as well as the outer sleeve and the second pipe are pressed into engagement with one another along the length of first overlap and the second overlap to define a pipe joint.
