Dorman's manifold converter eliminates the hassle of sourcing multiple parts — gaskets and hardware are included in the box for a straightforward, first-time repair. As a CARB-compliant unit, the 673-049 is the appropriate choice for vehicles registered in emissions-regulated states where a non-CARB alternative like the 674-049 would not be street-legal.
