In heavy-duty truck exhaust systems, it is used to route tubing around frame members, air tanks, or other components while maintaining smooth gas flow and reducing back pressure. Long radius elbows are preferred over short radius versions because they lower flow restriction and are less prone to cracking from thermal expansion. These are typically replaced when the original section is rusted through, dented, or when customizing an exhaust layout.
