The Dorman 672-8531 is a CARB-compliant manifold converter that combines an exhaust manifold and catalytic converter into a single, direct-fit replacement unit. Engineered to restore proper exhaust flow and emissions performance, this integrated assembly simplifies installation by eliminating the need for separate components.

Dorman designs this manifold converter as a precise OE-style replacement, manufactured to meet strict California Air Resources Board (CARB) emissions standards — making it legal for sale and use in California and all other U.S. states that follow CARB regulations.

Key Features:

• Combines exhaust manifold and catalytic converter in one integrated assembly
• CARB Compliant — meets California Air Resources Board emissions standards, legal in all 50 states
• Direct-fit OE-style replacement for simplified installation
• Manufactured to restore proper exhaust flow and reduce harmful emissions
• Helps resolve exhaust leaks, cracked manifolds, and catalytic converter failure simultaneously
• Built to withstand high exhaust temperatures and thermal cycling

The Dorman 672-8531 manifold converter is an ideal solution for restoring factory exhaust and emissions performance without the complexity or cost of sourcing and installing two separate components.
