What It Helps Repair

• Exhaust leaks at the manifold
• Cracked or warped original manifold surfaces
• Broken or missing manifold-to-downpipe connection hardware
• Noise from escaping exhaust gases
• Loss of proper exhaust sealing on the left side

Installation Notes

Verify left-side fitment before installation and compare the manifold port shape, gasket surface, and mounting points to the original part. Clean the cylinder head and exhaust flange surfaces thoroughly so the gasket can seal correctly. Use the included gasket and hardware during assembly, and inspect the downpipe connection for wear or distortion before final tightening.
