Catalytic Converter for Nissan Rogue Sport (2017-2022) 2.0L

Direct-Fit Exhaust Manifold Catalytic Converter for 2017-2022 Nissan Rogue Sport (J11)

What it Does: This direct-fit exhaust manifold catalytic converter replaces the integrated primary emissions assembly on the J11 Nissan Rogue Sport equipped with the MR20DD 2.0L I4 engine, restoring HC, CO, and NOx conversion while eliminating exhaust leaks and broken substrate rattles.

The Stock Nissan Rogue Exhaust Manifold & Catalyst Failure

On the J11 Rogue Sport powered by the MR20DD 2.0L engine, the factory exhaust manifold and primary catalytic converter mount directly to the cylinder head, exposing the ceramic brick to severe thermal cycling and heat soak. Repeated expansion and contraction fracture the internal honeycomb substrate or degrade the precious-metal washcoat over time. Once the core breaks apart or restricts flow, downstream oxygen sensor voltage mirrors upstream readings, triggering persistent P0420 efficiency codes, metallic rattling, and elevated exhaust backpressure.

Common Symptoms of a Failing OEM Catalytic Converter

• Catalyst Efficiency DTCs: Illuminated Check Engine Light storing P0420 or P0430 fault codes caused by depleted washcoat oxygen-storage capacity.
• Substrate Rattle & Exhaust Leaks: Audible metallic buzzing or rattling inside the manifold shell when the internal ceramic core fractures, often paired with flange ticking.
• Backpressure & Emissions Failure: Restricted exhaust flow causing sluggish acceleration, skewed fuel trims, and failed OBD-II emissions readiness checks.

The Direct-Fit Stainless Manifold Catalytic Converter Solution

This integrated manifold converter assembly uses a heavy-gauge stainless steel body and formed pipes to resist thermal cracking and road-salt corrosion. Inside the 8-inch by 5-inch housing, a high-flow ceramic honeycomb substrate coated with precious metals restores proper HC, CO, and NOx reduction for full OBD-II compliance. Built with factory cylinder-head and 3-bolt outlet flanges plus dual pre- and post-catalyst O2 sensor ports, the unit bolts directly onto the MR20DD cylinder head with zero cutting or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the J11 Rogue Sport?

Yes. This is a direct fit for the 2017-2022 Nissan Rogue Sport (S, SV, SL) equipped with the MR20DD 2.0L I4 engine. It does not fit the standard Nissan Rogue 2.5L, and because it is EPA federal (non-CARB) compliant, it is not legal for vehicles registered in California, New York, Colorado, or Maine.

Will this clear P0420/P0430 codes, and are O2 sensors included?

Yes, when the code is caused by a failed converter, though O2 sensors are not included. Installing a new direct-fit unit restores catalyst efficiency to clear P0420 and P0430 codes; inspect for exhaust leaks and transfer your existing oxygen sensors or install new sensors into the dual ports.

Are gaskets and mounting hardware included for installation?

Yes. The package includes the manifold gasket, 3-bolt flange gasket, ring seal, and mounting studs, bolts, washers, and nuts. Allow the exhaust to cool completely, soak seized fasteners with penetrating oil, torque all joints evenly, and check for leaks at startup.

The Nissan Emissions & OBD-II Precision Standard

Built for daily-driven J11 crossovers, this manifold converter restores factory-calibrated backpressure and clean catalyst monitoring without aftermarket ECU tuning. Reliable MR20DD exhaust scavenging keeps fuel trims balanced and ensures dependable, CEL-free emissions operation.
