AP Exhaust 771170 CARB Compliant OBD II Direct-Fit Catalytic Converter with Integrated Exhaust Manifold

The AP Exhaust 771170 is a CARB-compliant, OBD II-compatible catalytic converter with an integrated exhaust manifold, engineered as a direct-fit replacement for a precise, bolt-on installation. Built to exact OE dimensions, this manifold converter restores proper emissions function and exhaust flow without the need for cutting, welding, or modification.

AP Emissions Technologies manufactures this converter using ARISTO proprietary substrate chemistry, delivering highly efficient precious metal loadings for superior catalytic conversion efficiency. The advanced ceramic substrate — part of AP's "Clean by Design" philosophy — maximizes pollution reduction while meeting the stringent emissions standards required for CARB certification and OBD II monitor readiness.

Key Features:

• CARB Compliant — meets California Air Resources Board OBD II aftermarket catalytic converter requirements
• Direct-Fit Design — built to exact OE dimensions for a stock replacement fit with no modifications required
• Integrated Exhaust Manifold — combines the exhaust manifold and catalytic converter into a single, ready-to-install assembly
• ARISTO Ceramic Substrate — proprietary catalyst chemistry for maximum conversion efficiency and long service life
• Advanced Manufacturing — produced using automated workstations, spinner welding equipment, and high-speed production lines for consistent quality
• OBD II Compatible — engineered to satisfy OBD II catalyst efficiency monitor requirements and prevent check engine light codes
• Made in the U.S.A.

The AP Exhaust 771170 is a reliable, emissions-legal replacement for worn or failed OEM manifold converters, combining factory-correct fitment with proven catalytic technology for a clean, lasting repair.
