Dorman 674-305 Manifold Converter Exhaust Manifold with Integrated Catalytic Converter

The Dorman 674-305 is a direct-fit manifold converter that combines an exhaust manifold and catalytic converter into a single, integrated assembly. Engineered as a bolt-on replacement, this unit is designed to restore proper exhaust flow and emissions control function to your vehicle, matching the form, fit, and function of the original equipment part.

Dorman engineers this manifold converter using high-quality materials built to withstand the extreme heat and pressure cycles of the exhaust system. The integrated design simplifies installation by eliminating the need to replace the manifold and catalytic converter as separate components, saving time and reducing potential leak points.
