An exhaust flex pipe adds needed flexibility to your exhaust system, allowing it to bend instead of cracking and breaking. Also called flex joints or exhaust bellows, they’re an essential component of front wheel drive vehicles to absorb the rocking motions of the engine, They’re handy for custom exhaust builds, as well as competition vehicles that run hot and wild.

Flex pipes are usually found between the exhaust manifold and the down pipe. They can be as simple as a corrugated metal tube, or as complex as a multi-layer braided or woven metal lattice. Because they protect so many other parts, flex pipes tend to wear out more quickly than other exhaust components, and should be checked for leaks regularly on high-performance vehicles.

Summit Racing Equipment carries exhaust flex pipes in all the popular exhaust pipe diameters. Choose a convenient 4" to 14" length for sectioning into an existing system, or in bulk coil lengths for big custom fabrication projects.
