Detailed Description

This exhaust manifold is designed for front exhaust service on Nissan and INFINITI applications, including the Nissan Altima, Nissan Maxima, Nissan Murano, Nissan Quest, and INFINITI I35. Dorman 674-934 follows the original manifold’s fit and function for the listed vehicles, helping restore proper exhaust routing at the engine side while maintaining the correct oval-port configuration.

This part cross-references ATP 101480 for the same application. The cast iron body supports long-term exhaust heat exposure, while the included gasket, flange, studs, and nuts help complete the repair with the required sealing and attachment components.

What It Helps Repair

• Exhaust leaks at the manifold-to-cylinder head connection
• Cracked or warped original manifold housings
• Broken or missing manifold mounting studs and nuts
• Damaged sealing surfaces that can trigger exhaust noise or odor
• Front exhaust manifold failures on Nissan Altima, Maxima, Murano, Quest, and INFINITI I35 models

Installation Notes and Tips

Verify engine-side fitment by year, make, model, and front position before installation. Inspect the cylinder head sealing surface, fasteners, and downpipe connection for damage or corrosion, and replace worn mating components as needed to support a proper seal. Follow factory torque specifications and installation sequence for the best results.

Quality Assurance

This manifold is precision-engineered and durably manufactured to match original equipment fit and function on the specified vehicles. Dorman supplies this replacement as a regular-grade exhaust manifold for direct repair use.
