AP Exhaust 771131 CARB Compliant Direct Fit OBD-II Manifold Catalytic Converter

The AP Exhaust 771131 is a direct-fit, CARB-compliant exhaust manifold with integrated catalytic converter, engineered specifically for OBD-II equipped vehicles. This combined manifold-converter unit replaces the factory assembly with an OE-matching component that simplifies installation and restores proper emissions function.

AP Emissions Technologies utilizes the ARISTO substrate platform, featuring proprietary catalyst chemistry designed to deliver highly efficient precious metal loadings. The result is excellent converter efficiency and lower emissions output without sacrificing durability. The unit is constructed with a 409 stainless steel shell and neck for extended service life and resistance to exhaust heat and corrosion.

Key Features:

• CARB compliant — legal for sale and use in California and other CARB-adopting states
• Engineered specifically for OBD-II equipped vehicles to keep the MIL (check engine) light off
• Direct-fit design matches OE dimensions for straightforward installation
• Features "Clean By Design" ceramic substrates for maximum emissions reduction
• Increased precious metals loading for improved O2 storage and release
• 409 stainless steel shell and neck construction for long-term durability
• Built on advanced automated production lines using spinner welding equipment to ensure consistent quality
• 5-year/50,000-mile warranty on the converter body; 25,000-mile warranty on emissions performance

AP Emissions Technologies has been manufacturing exhaust and emissions components since 1927, producing converters to exact OE performance and reliability standards. Every unit undergoes strict quality control throughout engineering, development, and production to meet required emissions certifications.
