The HKS T51R exhaust manifold flange is a replacement flange designed to match T51R manifold outlets and downstream piping. It provides a correct mating surface for bolt-up during manifold or downpipe service, helping ensure a tight seal at the manifold-to-pipe interface and preventing exhaust leaks when reinstalling or modifying exhaust plumbing.
