Description
About the Toyota Tundra Catalytic Converter
The Toyota Tundra is Toyota’s full-size pickup truck, manufactured in San Antonio, Texas since 2007. The catalytic converter is a critical emissions control component installed in the exhaust system. Inside the converter, a ceramic honeycomb substrate coated with platinum, palladium, and rhodium converts harmful exhaust gases (carbon monoxide, nitrogen oxides, hydrocarbons) into less harmful carbon dioxide and water vapor. The Tundra typically has multiple catalytic converters: early models (1st gen 2000 to 2006) had two cats. Second-generation (2007 onward) and third-generation Tundras are equipped with four catalytic converters total (two per bank on the V8 engines). This unit is one of the cats; call to confirm which position (upstream or downstream, driver or passenger side) matches your needs.
Our used Tundra catalytic converter is built with high-grade stainless steel housing and ceramic honeycomb substrates, in spun-body construction. It is federal OBD-II compliant. CARB-compliant options are available for sale into California and the CARB compliance states (Colorado, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Mexico, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington). Always confirm CARB status at order if you live in a CARB compliance state.
Catalytic Converter Price Considerations for Tundra Owners
Tundra owners researching catalytic converter price for the 4.6L or 5.7L V8 face three primary options. New Toyota OEM dealer parts command the highest cat converter price tier, often well into four-figure territory per cat plus emissions-state-specific surcharges. Aftermarket new direct-fit catalytic converters (Walker, MagnaFlow, Eastern, AP Exhaust) provide a mid-tier alternative with federal-EPA or CARB compliance variants. Used OEM units like this listing sit at the most accessible catalytic converter replacement price point while still delivering substrate, flange, and heat-shield inspections that determine remaining service life. The Tundra V8 has four cats total (two per bank), so replacement scope (single cat vs full set) significantly affects total project cost. Call us for current pricing on this specific cat position.
Important Note About Catalytic Converter Theft
Toyota Tundras are among the most frequently targeted vehicles for catalytic converter theft due to part accessibility (high ground clearance) and high precious metal content. If your cat was stolen, we recommend taking immediate steps to deter future theft: installing an anti-theft device, parking in garages or well-lit areas, and etching your VIN on the new cat before installation. We can apply VIN-etching service on your replacement before shipping at no extra cost. Just provide your VIN at order.
Federal vs CARB Compliance: What You Need to Know
Federal EPA OBD-II compliance applies to catalytic converters sold and installed in 49 of the 50 US states. The CARB-compliance states (California plus Colorado, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Mexico, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington) have stricter emissions requirements than the federal baseline. A federal-EPA-compliant cat may not pass CARB emissions inspection in those states. If you live in a CARB state, confirm CARB-compliant status at order; we stock both federal-EPA and CARB-compliant variants. Tampering with the emissions system (removing, gutting, or installing a non-compliant cat) is a federal violation with fines up to $25,000 per violation, plus state-level penalties.
Signs Your Tundra Cat May Need Replacement
- Check Engine Light with codes P0420 or P0430 (catalyst efficiency below threshold)
- Visible damage to the cat housing (theft attempt, road debris strike)
- Loud roaring exhaust noise from underneath the truck (indicates damaged or removed cat)
- Sulfur or rotten egg smell from the exhaust
- Poor fuel economy combined with loss of power
- Failed state emissions inspection
- Complete theft of the original cat from underneath the truck
Things to Confirm Before Ordering
- Engine (4.6L V8 or 5.7L V8 on second-generation 2007-onward Tundras)
- Year (1st gen 2000 to 2006 vs 2nd gen 2007 onward have different cat configurations)
- Position needed (upstream / downstream, driver / passenger side bank)
- State of residence (federal EPA vs CARB compliance)
- VIN-etching service (request at order, no extra charge)
What Ships and What Does Not
You receive the OEM Tundra catalytic converter with stainless steel housing, ceramic honeycomb substrate, heat shields intact, and O2 sensor bungs in place (pre-cat and post-cat). VIN etching applied if requested at order. Not included: oxygen sensors (transfer from your old cat or source new), gaskets (replace at install, sold separately), exhaust hangers, and tools.
Vehicle Compatibility
This Toyota Tundra catalytic converter is compatible with the second-generation (2007 onward) and third-generation Tundras using the 4.6L V8 or 5.7L V8 engines. The first-generation Tundra (2000 to 2006) uses a different cat configuration with only two cats total; this listing applies to the 4-cat second and third generations. Always call (855) 634-4447 with your VIN before ordering to confirm exact fitment for your specific year and position.
Inspection Workflow
Every used Tundra catalytic converter we ship goes through this process:
- Visual inspection of housing for cracks, dents, or impact damage
- Substrate integrity check (no internal cracking visible from inspection port)
- Heat shield condition verified (intact and securely attached)
- O2 sensor bungs inspected (pre-cat and post-cat threads clean)
- Federal EPA OBD-II compliance verified
- CARB compliance status documented (compliant or not, varies by donor)
- Donor application and year documented when available
These are used OEM cats. Surface oxidation and exterior weathering are normal on used parts and disclosed before shipping. Internal substrate condition and emissions performance are the critical factors and are inspected on every unit.

Three pricing tiers. New Toyota OEM dealer parts command the highest cat converter price tier, often well into four-figure territory per cat plus emissions-state-specific surcharges. Aftermarket new direct-fit converters (Walker, MagnaFlow, Eastern, AP Exhaust) sit at a mid-tier with federal-EPA or CARB compliance variants. Used OEM units like this listing offer the most accessible catalytic converter replacement price while still delivering verified substrate, heat shield, and O2 bung condition. The Tundra V8 has four cats total, so replacement scope (single vs full set) significantly affects total project cost.
Three factors. First, the Tundra's high ground clearance makes the cats accessible without a jack. Second, the cats contain valuable precious metals (platinum, palladium, rhodium) that scrap dealers will buy. Third, the cats are large units with significant metal content per cat. We strongly recommend VIN-etching the new cat before installation (free service from us on request), parking in garages or well-lit areas, and installing an aftermarket anti-theft device like a CatClamp or MillerCAT shield.
Emissions stringency. Federal EPA OBD-II compliance applies to catalytic converters sold and installed in 49 of the 50 US states. The CARB-compliance states (California plus Colorado, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Mexico, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington) have stricter emissions requirements. A federal-EPA-compliant cat may not pass CARB emissions inspection in those states. Always confirm CARB status at order if you live in a CARB state.
No. Tampering with the emissions system (removing, gutting, replacing with a straight pipe, or installing a non-compliant cat) is a federal violation with fines up to $25,000 per violation under the Clean Air Act, plus state-level penalties. Some states also impose vehicle registration suspension. Always install a compliant replacement; we offer federal-EPA and CARB-compliant options to match your state.
Four catalytic converters total. The 4.6L V8 and 5.7L V8 each have two cats per bank (upstream pre-cat and downstream main cat), for four cats total. The first-generation Tundra (2000 to 2006) used a different configuration with only two cats. When ordering, specify which position you need (upstream/downstream, driver/passenger side bank). We confirm position before shipping.
100,000 to 200,000 miles under normal conditions. Catalytic converters degrade as the precious metal coating slowly converts to less effective forms over time. Premature failure typically results from engine issues that contaminate the substrate: engine misfires (unburned fuel burns inside the cat, melting the substrate), oil burning (oil contaminates the precious metal coating), coolant leaks into the exhaust, or operating with leaded fuel. Address upstream engine issues before installing a new cat to protect your investment.
No. The 4.6L V8 and 5.7L V8 have different exhaust manifold flange dimensions and different cat sizing. Always confirm engine when ordering. We stock cats for both engines.
Strongly recommended at high mileage. Oxygen sensors age along with the cat and often near end-of-life at the same time. New cat performance can be compromised by aged sensors providing incorrect feedback to the ECM. Sensor cost is small relative to the cat; replacing both at the same labor visit makes economic sense for trucks past 100,000 miles. Sensors are sold separately.
