Catalytic Converter for Acura RDX (2013-2017) 3.5L Front Left & Right

Direct-Fit Replacement Front Catalytic Converter Set for 2013-2017 Acura RDX (TB3/TB4)

What it Does: The Front Catalytic Converter Set replaces worn or clogged bank 1 and bank 2 manifold converters on the 2013-2017 Acura RDX to restore exhaust velocity, clear P0420/P0430 trouble codes, and maintain proper emissions compliance.

The Stock Acura RDX Manifold Converter Vulnerability

Factory close-coupled manifold converters on the J35Y2 3.5L V6 are mounted directly to the cylinder heads, exposing them to continuous thermal shock and violent exhaust pulsing. Over high mileage cycles, oil blow-by associated with the factory VCM (Variable Cylinder Management) system fouls the precious metal washcoat, leading to substrate poisoning, core melt-down, and face-plugging. This restriction increases exhaust backpressure, spikes cylinder head temperatures, robs the TB3/TB4 platform of fuel efficiency, and triggers persistent catalyst efficiency DTC faults.

The Engineering Solution

Manufactured as a heavy-duty direct replacement, this manifold converter pair features corrosion-resistant stainless steel shells engineered to resist thermal distortion under severe operating loads. Internally, a durable ceramic honeycomb substrate provides optimal surface-area-to-volume ratio, facilitating chemical reduction and oxidation reactions without bottlenecking exhaust flow dynamics. Precision robotic welds and rigid connection flanges align with the factory cylinder head and flex-pipe attachment points. Note: The unit does not fit the factory heat shield perfectly, and slight shield modification may be required during installation.

Frequently Asked Questions & Fitment Warnings

Does this fit the TB3/TB4 RDX?

Yes, this is a direct fit for the 2013-2017 Acura RDX equipped with the J35Y2 engine. Not legal for sale, installation, or use on vehicles registered in California or New York emissions standard states.

Do original heat shields bolt directly back on?

No, the unit does not fit the factory heat shield perfectly, so minor trimming or adjustment of the original heat shields is required during professional installation.
