What Is an Exhaust Flex Pipe?
Exhaust flex pipes are a flexible metal pipe sections that are used either in areas where an exhaust pipe needs to be flexible, or to repair a damaged exhaust system. While they are all-metal, it is common for one to fail and require replacement.
Automotive exhaust pipes get extremely hot from the exhaust gas passing through the system and out the tailpipe. Due to this, when an exhaust system needs to bend, shift or be flexible, the manufacturer cannot use traditional materials like rubber. The flex pipe is made of metal strips woven into a lattice, and thus can withstand exhaust gas heat. Higher quality flex pipes will be made of stainless steel.
Automotive engines move slightly during operation, whereas most exhaust systems are fixed from the mid-section back. Flex pipes allow the engine to move and not crack or rupture what would otherwise be an inflexible metal exhaust pipe. Flex pipes are typically found where the exhaust manifold meets the downpipe or mid-section of an exhaust, which is closer to the engine than to the exit tailpipe.
Exhaust flex pipe sections are widely available at automotive stores in a variety of lengths and diameters.
