Eastern Convertors 41270 Catalytic Converter with Integrated Exhaust Manifold - Front Right

Direct-Fit Catalytic Converter for Lexus Front Right

Eastern Convertors DIRECT FIT Part Number 41270 is a Federal / EPA direct-fit manifold catalytic converter built for specific Lexus front-right applications. It is engineered to match OE dimensions and fitment for straightforward replacement on select Lexus IS250, IS350, GS350, and RC350 models.

The DIRECT FIT product line focuses on exact-fit exhaust replacement parts, and this unit uses advanced manufacturing methods with automated production and spinner welding to help maintain consistent dimensions. The ECO III catalyst design and NANO substrate chemistry are used to support efficient converter loading while keeping the part cost-conscious for repair work.

What This Part Helps Address

• Failed or inefficient catalytic converter on the front-right exhaust bank
• Check engine light concerns related to catalyst efficiency
• Exhaust manifold replacement needs on select Lexus V6 applications
• Emissions inspection failures tied to converter performance
• Fitment issues from a damaged or corroded OE-style manifold converter

Installation Notes

Verify the vehicle’s emissions certification and state restrictions before ordering, since this part is not approved for certain California-emissions applications in CA, NY, CO, and Maine as listed in the fitment notes. Confirm the front-right position, O2 sensor locations, and flange style before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to OE dimensions and fitment standards. The NANO substrate chemistry is used to support efficient catalyst loading and consistent converter performance across the DIRECT FIT line.
