AP Exhaust 754230 Catalytic Converter with Integrated Exhaust Manifold - Front

CARB-Compliant Direct-Fit Manifold Converter

AP Exhaust 754230 is a catalytic converter with integrated exhaust manifold built for direct-fit replacement on select Honda Civic front applications. It uses a stainless steel body, a ceramic substrate, and CARB-compliant calibration to match the listed California emissions requirements.

AP Exhaust’s 1HNXV01.7YJ9 product line focuses on OE-style fitment and manufacturing consistency, with automated production methods and welded construction used to hold dimensions to original equipment specifications.

Key Features

• Part number 754230 for select Honda Civic front applications
• CARB compliant direct-fit manifold with Executive Order D-280-102
• Stainless steel body for exhaust-side durability
• Ceramic substrate material
• 6-bolt welded flange inlet and 2-bolt welded flange outlet
• Overall length: 15.38 in.
• Built to OE dimensions for direct replacement fitment

Detailed Description

This AP Exhaust catalytic converter with integrated exhaust manifold is engineered for front-position Honda Civic applications from 2001 through 2005, including 2001 Honda Civic, front; 2002 Honda Civic, front; 2003 Honda Civic, front; 2004 Honda Civic, front; and 2005 Honda Civic, front. It is a CARB-compliant direct-fit manifold with EO number D-280-102, making it appropriate for vehicles that must meet California emissions requirements.

The 754230 uses a stainless steel housing and ceramic substrate to support efficient exhaust aftertreatment while maintaining OE-style dimensions and fitment. The AP Exhaust 1HNXV01.7YJ9 line is built with controlled manufacturing processes to help keep the converter aligned with original equipment mounting points and flange configuration. This part cross-references AirTek, Inc. (e.g., 1HNXV01.7YJ9) for the same application.

Common Problems This Part Addresses

• Failed emissions test due to a worn or inefficient converter
• Check engine light related to catalyst efficiency codes
• Exhaust leaks at the manifold or flange connection
• Restricted exhaust flow from a damaged substrate
• Replacement need after corrosion or heat damage in the front exhaust section

Installation Notes and Tips

Verify the vehicle’s emissions label and EO requirements before installation. Confirm the front-position application, flange style, and OE reference number against the existing part to ensure correct match-up. Because this is an integrated manifold converter, inspect adjoining exhaust components, gaskets, and mounting surfaces for wear or damage before assembly.

Compatible With 2001-2005 Honda Civic, front. Also listed for 2001 Honda Civic front, 2002 Honda Civic front, 2003 Honda Civic front, 2004 Honda Civic front, and 2005 Honda Civic front applications with the noted OE reference numbers.

Quality Assurance

AP Exhaust uses advanced manufacturing methods, including automated workstations, spinner welding equipment, and high-speed production lines, to build converters to exact OE dimensions and fitment. The proprietary substrate chemistry is used to support efficient catalyst loading and consistent converter performance within the stated CARB-compliant application.
