## Overview

This 2.25" universal high flow catalytic converter features a stainless steel housing and dual-layer ceramic honeycomb substrate coated with platinum, palladium, and rhodium. Designed for vehicles under 3.0L, it delivers a verified 4-7% improvement in fuel efficiency while meeting EPA and OBD3 emissions standards. The direct-fit model addresses P0420 engine codes and includes a heat shield and O2 sensor port for seamless OEM integration. Backed by a 2-year/50,000-mile warranty, it offers a durable, cost-effective solution for enhanced engine performance and reduced emissions.

## Description

Core FunctionCatalytically convert the three main harmful substances in engine exhaust gases: Carbon monoxide (CO) → Carbon dioxide (CO₂)Hydrocarbons (HC) → Water (H₂O) and carbon dioxide (CO₂)Nitrogen oxides (NOx) → Nitrogen (N₂) and oxygen (O₂) Structure and PrincipleCarrier: Honeycomb-shaped ceramic or metal structure, with the surface coated with catalysts (such as platinum, palladium, rhodium and other precious metals). Catalytic reaction:Reduction reaction: Treat NOx, decomposing it into nitrogen and oxygen.Oxidation reaction: Treat CO and HC, converting them into carbon dioxide and water.Working conditions: High temperature and appropriate air-fuel ratio, with oxygen sensors for control. Common causes of faultsFuel/oil issues:Low-quality fuel containing sulfur, lead, or oil combustion residues can cause the catalyst to become "poisoned".Carbon deposits blockage: Long-term low-speed driving or incomplete fuel combustion can lead to blockage.Physical damage: Bumping or high-temperature sintering can cause the carrier to break.Abnormal mixture: Imbalanced air-fuel ratio (such as fuel injection failure) can cause the catalytic converter to overheat and fail. Symptoms of the malfunction:- A pungent odor in the exhaust and excessive emissions.- Reduced engine power and increased fuel consumption.- Warning lights on the dashboard (such as an OBD indication of low catalytic converter efficiency,P0420,P0430). Maintenance suggestions:Use genuine fuel and low ash engine oil to prevent impurities from damaging the catalyst.Regularly inspect the ignition/fuel injection system to prevent overly rich mixture or misfire.After long-distance driving, run the vehicle at a moderate high speed to help burn off carbon deposits.Avoid driving through water or dragging the undercarriage to prevent damage to the carrier. Replacement costThe original factory catalytic converter is relatively expensive (hundreds to thousands of dollars) due to the presence of precious metals.OEM parts or repair solutions are less costly, but compliance should be taken into account.Note: If the vehicle fails the annual inspection due to a failed catalytic converter, it is recommended to first check the oxygen sensor or clean the carbon deposits, as a direct replacement may not be necessary.

Review: Great performance - Good quality construction, ease of installation. The catalytic converter provides great performance. I would consider this to be value for money. The performance and sound quality has improved
Review: Still works - Works great

## Features

- Regional Sales Restrictions: This product is not approved for use in vehicles registered in California (CARB-compliant), Colorado, New York, or Maine due to stricter emissions regulations (e.g., Euro V/VI or CARB Tier 3 standards). The product fully complies with OBD3 emissions standards, ensuring catalytic efficiency and durability meet U.S. federal EPA requirements.
- Fault Remediation & Direct Replacement: Designed to address P0420 engine codes (catalytic efficiency below threshold) or catalytic converter theft scenarios. Engineered for seamless integration with OEM interfaces, factory pre-tested for guaranteed compatibility with your vehicle to eliminate exhaust leaks, abnormal noise, and system malfunctions.
- Universal Specifications: 2.25-inch inlet/outlet diameter (outer), 13-inch total length. Compatible with most vehicles under 3.0L displacement. Users are advised to verify original exhaust pipe dimensions prior to installation. For engines 3.0L or larger, a parallel dual-catalyst welding configuration is recommended to prevent exhaust flow overload and subsequent P0420 fault triggers.
- Performance Upgrade: Stainless steel housing paired with a dual-layer high-temperature-resistant ceramic honeycomb substrate increases catalytic surface area and optimizes exhaust flow velocity, reducing backpressure for enhanced engine power and fuel efficiency (verified 4-7% improvement in real-world testing). Industry-leading precious metal coating (platinum, palladium, rhodium) ensures maximum conversion efficiency of CO, HC, and NOx emissions, achieving near-Euro IV cleanliness levels and contributing to PM2.5 particulate reduction.
- Worry-Free Purchase: Backed by a 2-year/50,000-mile warranty covering core functional failures, material defects, and manufacturing flaws. Every unit undergoes rigorous pre-shipment testing to ensure performance reliability and regulatory compliance, delivering peace of mind throughout the product lifecycle.
