• Addressing exhaust leaks on the right side of the engine
• Correcting noise caused by manifold gasket failure
• Repairing damaged manifold mounting surfaces

Installation Notes and Tips

Verify right-side fitment before installation and compare the manifold port layout, mounting hole count, and collector dimensions to the original part. The included gaskets should be replaced during installation to help achieve a proper seal. Inspect the mating surfaces, fasteners, and downpipe connection points for wear or damage before assembly. Because this manifold does not include mounting hardware, reuse or source the required hardware separately as needed.
