Dorman 674-6011 HD Solutions Exhaust Flex Bellow Kit 4 in. x 16.80 in. Clamp-On

The Dorman 674-6011 Exhaust Flex Bellow Kit is a heavy-duty replacement exhaust bellow, also known as a flex pipe, designed as a direct-fit replacement for the original equipment pipe on select International trucks. Engineered under Dorman's HD Solutions line, this steel bellow is built to handle the rigorous demands of commercial truck exhaust systems.

This flex bellow provides a critical flex point in the exhaust system, absorbing displacements, vibrations, and thermal expansion caused by extreme exhaust temperatures. By maintaining a proper seal between the engine and after-treatment emissions equipment, it helps prevent exhaust leaks that can rob the engine of efficiency and power.
