Catalytic Converter for BMW X2 (2018-2022) 2.0L

Direct-Fit Catalytic Converter for 2018-2022 BMW X2 (F39)

What it Does: This direct-fit catalytic converter bolts behind the turbocharger on 2018-2022 BMW X2 (F39) B46/B48 2.0L models to restore emissions conversion and clear catalyst codes.

The Stock BMW X2 Catalytic Converter Failure

Mounted at the turbocharger outlet, the OEM converter on the F39 chassis with the B46/B48 2.0L Turbo I4 endures extreme thermal cycling. Repeated heat soak degrades the washcoat and fractures the ceramic core, causing the substrate to rattle inside the shell. Once conversion efficiency drops or broken honeycomb restricts exhaust flow, the DME triggers P0420/P0430 codes and elevates backpressure.

Common Symptoms of a Failing OEM Catalytic Converter

• Check Engine Light: Stored P0420 or P0430 catalyst efficiency fault codes in the DME.
• Exhaust Rattle: Metallic noise at idle or deceleration from a fractured ceramic substrate.
• Flow Restriction: Sluggish turbo spool, elevated backpressure, and failed OBD-II emissions readiness.

The Direct-Fit Stainless Catalytic Converter Solution

Constructed with a rust-resistant stainless steel body and pipes, this direct-fit unit prevents heat cracking and structural fatigue. Its 8 in x 5 in canister houses a ceramic honeycomb substrate with a precious-metal washcoat to convert HC, CO, and NOx. Featuring a factory turbo-side inlet, flex joint, support bracket, and two O2 sensor ports, it bolts on without cutting or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the F39 X2?

Yes. Fits 2018-2022 BMW X2 sDrive28i, xDrive28i, and M35i with the B46/B48 2.0L engine. Excludes sDrive20i, diesels, and CARB states (CA, NY, CO, ME).

Will this clear P0420/P0430 codes and include O2 sensors?

Clears P0420/P0430 from failed converters; O2 sensors not included. Transfer or replace sensors and inspect for exhaust leaks.

What installation prep ensures a leak-free seal?

Cool exhaust fully and apply penetrating oil to fasteners. Compare parts first, use new gaskets, torque evenly, and leak-check joints.
