Catalytic Converter for Lexus RX350 (2007-2009) 3.5L Bank 1 & Bank 2

Direct-Fit Manifold Catalytic Converter Set for 2007-2009 Lexus RX (XU30)

What it Does: The Direct-Fit Manifold Catalytic Converter Set replaces worn factory exhaust manifolds on the 2007-2009 Lexus RX to restore exhaust gas velocity, resolve check engine codes, and maintain proper emissions compliance.

The Stock Lexus RX Catalyst Degradation

With sustained mileage and thousands of thermal cycles, the factory ceramic substrate inside the XU30 exhaust manifolds experiences washcoat degradation and structural breakdown. Carbon buildup, thermal shock, and age-related sintering reduce catalytic reduction efficiency, leading to restricted exhaust scavenging, elevated backpressure, loss of fuel economy, and persistent P0420 and P0430 diagnostic trouble codes.

The Engineering Solution

Engineered as a direct bolt-on replacement for both Bank 1 and Bank 2 manifolds, this assembly features heavy-gauge stainless steel construction engineered to withstand extreme thermal expansion without cracking. Internally, a high-efficiency ceramic honeycomb core coated in precious metals ensures optimal oxidation of carbon monoxide and hydrocarbons while reducing nitrogen oxides. Precision laser-cut flanges, OE-location oxygen sensor bungs, and factory-matched hanger provisions enable direct installation without cutting, heating, or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the XU30 RX?

Yes, this is a direct fit for the 2007-2009 Lexus RX equipped with the 2GR-FE engine. This is an EPA-compliant federal catalytic converter set; it is not legal for sale, installation, or use on vehicles licensed in California, Colorado, New York, or Maine.

Do I need to correct engine misfires before installation?

Yes, raw fuel entering the exhaust stream from misfires, bad ignition coils, or oil burning will instantly overheat and melt new catalytic substrate cores.

The Lexus Standard

Restoring proper exhaust flow and clean tailpipe emissions is critical to preserving the refined, smooth closed-loop power delivery engineered into the Lexus luxury platform.
