Detailed Description

Eastern Convertors 40608 is a direct replacement catalytic converter for select Acura RSX and Honda Civic models. It is built to OE dimensions using automated production processes, spinner welding equipment, and high-speed manufacturing lines to support consistent fitment and repeatable assembly quality. The ECO II catalyst design and proprietary NANO substrate chemistry are used to improve converter efficiency while keeping production costs controlled.

This part is a strong match for drivers searching for a 2002-2006 Acura RSX catalytic converter, a 2002-2005 Honda Civic catalytic converter, or Eastern Convertors 40608 for an undercar exhaust repair. It is a Federal / EPA unit and is not for sale or use in California, Colorado, Maine, or New York for vehicles with CA emissions.

What It Helps Fix

• Failed emissions test caused by a worn catalytic converter
• Check engine light related to catalyst efficiency codes
• Restricted exhaust flow from a deteriorated converter core
• Exhaust odor from a converter that is no longer functioning properly
• Fitment issues when replacing a factory undercar converter on Civic or RSX models

Installation Notes and Tips

Verify the vehicle’s emissions configuration before ordering, since this Federal / EPA converter is not approved for CA-emissions vehicles in CA, CO, ME, or NY. Confirm the inlet and outlet flange styles, O2 sensor port count, and overall length against the original part before installation. Because this is a direct-fit undercar converter, it is intended to align with factory-style exhaust routing on the listed Acura RSX and Honda Civic applications.

Quality Assurance

Eastern Convertors uses automated workstations and controlled production processes to build converters to exact OE dimensions and fitment. The 40608 catalytic converter is manufactured with efficiency-focused substrate chemistry and OE-style construction for consistent replacement performance.
