Keep your exhaust flange joints tight and flexing quietly with the AP Exhaust Exhaust Spring (P/N 4979). This spring-bolt tension spring seats over an exhaust flange stud to hold two pipe sections together, maintaining clamping load on the joint while allowing the exhaust to shift slightly with engine movement and heat expansion. It's a direct-fit replacement across a wide range of applications, including the 2015-2018 Chevrolet City Express [L4-2.0L], 2002-2006 Nissan Altima [L4-2.5L], 2013-2020 Nissan Pathfinder [V6-3.5L], 2003-2023 Toyota 4Runner [V6-4.0L], 2012-2017 Toyota Camry [L4-2.5L], 2003-2019 Toyota Corolla [L4-1.8L] and many more — see the Buyer's Guide tab for the full list.

  • Spring-loaded joint hardware: maintains tension on a flanged exhaust connection so the pipes stay seated while permitting slight movement.
  • Quantity per application: the listed applications call for 1; sold as a single spring.
  • Country of origin: India.

A worn or broken exhaust spring can let a flange joint loosen, resulting in an exhaust leak, ticking or hissing at the connection, or a rattle from the joint. If a failed spring at the flange is the cause, this replaces it. Confirm the correct engine and application before ordering.
