Catalytic Converter for Toyota Tundra (2007-2019) 5.7L Left & Right

Direct-Fit Catalytic Converter Assembly for 2007-2019 Toyota Tundra

What it Does: The Left & Right Catalytic Converter Set replaces deteriorated factory exhaust emissions units on the 2007-2019 Toyota Tundra 5.7L to restore exhaust gas velocity, resolve catalytic inefficiency codes, and lower exhaust backpressure.

The Stock Toyota Tundra Exhaust Degradation

Under heavy towing and sustained payloads, the factory catalytic converters on the XK50 platform experience extreme thermal cycling. Over time, internal ceramic monoliths fracture, suffer washcoat depletion, or clog with carbon deposits. This substrate breakdown triggers persistent P0420 and P0430 diagnostic trouble codes (DTCs), chokes exhaust scavenge efficiency, and elevates exhaust gas temperatures (EGT), ultimately robbing the 3UR-FE V8 of mid-range torque and fuel efficiency.

The Engineering Solution

Engineered as a bolt-on dual bank replacement, this catalytic assembly uses heavy-gauge tubular stainless steel construction for optimal thermal retention and corrosion resistance. Inside, a high-porosity ceramic honeycomb substrate loaded with an efficient precious-metal washcoat maximizes surface area contact to eliminate tailpipe emissions without throttling exhaust flow. Precision-stamped OEM-spec thick flanges eliminate warping under load, while factory-located O2 sensor bungs allow seamless plug-and-play installation of primary and downstream oxygen sensors. Includes high-temp exhaust seals and installation hardware to ensure an airtight seal against the exhaust manifolds and intermediate pipes.

Frequently Asked Questions

Does this fit the XK50 Tundra?
Yes, this assembly is engineered specifically as a direct replacement for the 2007-2019 Toyota Tundra XK50 equipped with the 5.7L 3UR-FE engine.

Will this resolve P0420 and P0430 check engine lights?
Yes, assuming no upstream engine misfires, vacuum leaks, or bad O2 sensors exist, this fresh catalyst substrate clears catalytic efficiency trouble codes.
