Catalytic Converter for Scion tC (2006-2010) 2.4L

Direct-Fit Stainless Catalytic Converter for 2006-2010 Scion tC (ANT10)

What it Does: Replaces the integrated manifold and catalytic converter on 2006-2010 Scion tC (ANT10) 2AZ-FE 2.4L engines to restore emissions conversion and flow.

The Stock Scion tC Manifold Failure

On the ANT10 Scion tC with the 2AZ-FE 2.4L engine, the factory exhaust manifold and catalyst share one close-coupled assembly bolted directly to the cylinder head. Repeated thermal cycling and engine oil consumption subject the ceramic brick to severe heat soak, causing washcoat poisoning and substrate fracture. Once degraded, rear O2 readings mirror front fluctuations, triggering P0420/P0430 catalyst efficiency faults and restricting exhaust scavenging.

Common Symptoms of a Failing OEM Converter

• Check Engine Light: Stored P0420/P0430 codes from depleted catalyst oxygen storage.
• Metallic Rattle: Engine-bay clatter caused by a fractured ceramic substrate.
• Emissions Failure: Elevated backpressure and failed OBD-II readiness from a clogged brick.

The Direct-Fit Stainless Solution

Built with stainless steel piping and a precision-welded body, this manifold-converter assembly resists heat cracking while matching factory port alignment. Inside, a ceramic honeycomb substrate with a precious-metal washcoat converts HC, CO, and NOx emissions to satisfy OBD-II thresholds. Factory-style cylinder head flanges, brackets, an upstream O2 sensor bung, and a spring-bolt outlet joint ensure a direct bolt-on seal without welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the ANT10 tC?

Yes. Fits 2006-2010 Scion tC 2AZ-FE 2.4L models. Excludes 2011-2016 2.5L models; EPA federal only (not CARB approved; not legal in CA, NY, CO, ME).

Will this clear P0420/P0430 codes? Are O2 sensors included?

Yes for catalyst faults; sensors are not included. It restores efficiency to clear P0420/P0430 codes—check for leaks and reuse or replace O2 sensors.

Are gaskets and hardware included?

Yes. Manifold gasket, outlet ring gasket, and spring bolts are included; soak fasteners with penetrating oil and torque evenly.

The Scion Performance Standard

Built for the ANT10 chassis, this converter restores flow efficiency and throttle response on the 2AZ-FE engine. Factory tolerances ensure CEL-free operation without cutting or welding.
