Catalytic Converter for Hyundai Santa Fe (2007-2009) 3.3L Rear Left & Right

Direct-Fit Rear Catalytic Converter for 2007-2009 Hyundai Santa Fe

What it Does: The direct-fit rear catalytic converter replaces degraded factory emissions cores on the 2007-2009 Hyundai Santa Fe to eliminate P0420/P0430 diagnostic trouble codes and restore proper exhaust flow.

The Stock Hyundai Santa Fe Substrate Degradation

Over extended operating cycles, the factory emissions units on the CM platform succumb to severe thermal fatigue and carbon contamination. Exhaust backpressure builds as the OEM washcoat deteriorates, resulting in ceramic monolith fracture, elevated tailpipe emissions, and persistent CEL triggers. Restrictive factory degradation hampers exhaust scavenging on the Lambda G6DB V6, leading to sluggish low-end torque and reduced engine efficiency.

The Engineering Solution

Engineered to drop straight into the rear exhaust tract, this catalytic converter assembly utilizes high-grade, corrosion-resistant stainless steel piping built to withstand road salts and intense thermal cycling. Inside, a high-efficiency ceramic substrate maximizes surface area for precious metal contact, promoting thorough catalytic conversion without choking exhaust gas velocity. Robotically welded flanges and factory-profile hanger provisions eliminate the need for custom fabrication or cutting, mating directly with OEM hardware (interchange reference 16604).
