Dorman 674-6005 Exhaust Flex Bellows Kit

The Dorman 674-6005 Flex Bellows Kit is a heavy-duty exhaust system component designed to provide a critical flex point between the engine and after-treatment emissions equipment. This exhaust pipe bellow is engineered to absorb displacements, vibrations, and thermal expansion from extreme exhaust temperatures, helping to prevent exhaust leaks and loss of engine power.

Key Features:

• Complete installation kit includes all hardware required for a direct-fit replacement
• Quality-engineered steel construction designed for heavy-duty truck applications
• 5.00-inch inlet diameter with 16.5-inch overall length
• Clamp-on design for easier installation
• Rigorously tested for vehicle fitment and material performance
• Direct replacement for original equipment exhaust bellows

This flex pipe has undergone comprehensive vehicle fitment and material testing to ensure proper fit and reliable performance. The bellows design allows the exhaust system to flex and move with the engine, reducing stress on exhaust components while maintaining a secure seal throughout the system.
