Product Details

Part Number 40721 is engineered for the firewall-side front right position on the Toyota Camry and Lexus ES300 listed above. The DIRECT FIT product line focuses on OE-matched dimensions and fitment, while the manufacturer’s production process uses automated workstations, spinner welding, and high-speed manufacturing to maintain consistent build quality. The converter also uses proprietary NANO substrate chemistry to support efficient catalyst loading and lower-cost production without changing the direct-fit application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Failed emissions test or catalyst efficiency fault
• Rattling, cracked, or damaged manifold converter assembly
• Exhaust leak at the manifold or flange connection
• Check engine light related to catalyst or O2 sensor performance
• Corrosion or heat damage in the front exhaust section

Installation Notes

Verify the vehicle’s emissions certification before ordering. This Federal / EPA direct-fit manifold is not for sale or use in California, Colorado, Maine, or New York on vehicles with CA emissions. Confirm the front right, firewall-side location, the 6-bolt welded inlet, the 2-bolt welded outlet, and the single O2 sensor port before installation.

Quality Assurance

Eastern Convertors builds this DIRECT FIT converter to OE dimensions using controlled manufacturing processes for consistent fitment and repeatable assembly quality. The ECO III catalyst and NANO substrate chemistry are used to support efficient converter performance in the specified application.
