Installation Notes and Tips

Verify thread size, stud length, and vehicle application before installation. Clean the manifold and cylinder head mounting surfaces, and inspect the threads in the engine and manifold for damage before installing the new hardware. Because exhaust fasteners are exposed to heat cycling, proper torque and even tightening are important for a stable seal.
