Product Details

The Eastern Convertors DIRECT FIT line focuses on application-specific exhaust replacement parts that match original equipment dimensions and mounting points. Part number 40847 uses advanced manufacturing methods, including automated production and spinner welding, to maintain consistent fit and efficient production. The converter also uses the brand’s NANO substrate chemistry to support efficient catalyst loading and value-focused construction. This makes Eastern Convertors 40847 a practical replacement for a worn or failed rear catalytic converter on the Lexus SC430.

Compatible With: 2002-2010 Lexus SC430, rear undercar Y-pipe unit. This part cross-references OE-style replacement applications for the same vehicle platform.

What It Helps Address

• Check engine light related to catalyst efficiency faults
• Exhaust leaks at the rear converter/Y-pipe assembly
• Restricted exhaust flow from a deteriorated converter
• Failed emissions inspection caused by a damaged catalytic converter
• Noise or odor concerns from a compromised exhaust aftertreatment unit

Installation Notes and Tips

Verify the rear undercar configuration before ordering. This unit uses 2-bolt welded inlet and outlet connections and is specified with two O2 sensor ports. Confirm the vehicle is not a California-emissions application in California, Colorado, Maine, or New York, as noted for this part. Compare the original converter and Y-pipe layout to confirm match before installation on the Lexus SC430.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions and fitment targets. The DIRECT FIT line is engineered for consistent installation and application-specific replacement performance.
