Product Line Details

Davico Exact-Fit Catalytic Converter parts are built around OE sample parts so the converter matches the original fit and function more closely than a universal replacement. Part number 18442 is part of this exact-fit line for drivers servicing a Mercedes-Benz S550 left-side exhaust application.

Detailed Description

This catalytic converter is made for the 2007-2011 Mercedes-Benz S550, left side, and is shaped to follow the factory exhaust routing. Davico 18442 uses a 2-bolt spin flange inlet, slip-fit outlet, and provisions for 2 O2 sensors, making it a direct replacement choice for restoring exhaust system function on OBDII vehicles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Check engine light concerns related to catalyst efficiency
• Failed emissions testing caused by a worn converter
• Exhaust restriction from a deteriorated catalyst substrate
• Factory-fit issues after replacing a damaged left-side converter
• Leak points at worn flange or slip-fit connections

Installation Notes

Compatible With 2007-2011 Mercedes-Benz S550, left. Verify the vehicle’s emission configuration before installation: not legal for use in California, and illegal for installation in New York on vehicles equipped with California emission systems. Confirm sensor count, inlet style, outlet style, and overall length against the original unit before assembly.

Quality Assurance

Davico designs Exact-Fit Catalytic Converters using OE sample parts and emissions-reducing catalyst materials selected for current OBDII vehicle demands. Part number 18442 is built to support proper fitment and exhaust system function on the specified Mercedes-Benz S550 application.
