1. A bellows for use in an exhaust system, the bellows comprising:
a first opening and a second opening, both the first opening and the second opening configured to connect to the exhaust system; and
a plurality of convolutions extending between the first opening and the second opening, the plurality of convolutions varying in height, the plurality of convolutions arranged to form a curved plane, the curve plane being concave in shape along the entire length of the bellows;
wherein the plurality of convolutions extending in heights provide for increased lateral movement in the same axial space compared to a bellows without convolutions varying in height.
