MagnaFlow Universal Catalytic Converter California Grade CARB Compliant 447176 – Stainless Steel 2.5in Inlet/Outlet Diameter, 11.5in Overall Length, No O2 Sensor – CA Legal Replacement

Description

Product Overview

The MagnaFlow 447176 Universal Catalytic Converter is engineered to meet the stringent requirements of California’s CARB OBDII emissions program, making it a legal replacement for vehicles operating in the most regulated markets. Crafted from high‑grade stainless steel, the converter offers exceptional corrosion resistance, ensuring a long service life even in harsh environments such as coastal regions with salty air or areas with extreme temperature fluctuations. Its 2.5‑inch inlet and outlet diameters provide a balanced flow rate that supports optimal exhaust scavenging while maintaining the necessary catalytic activity to reduce harmful pollutants.

Measuring 11.5 inches in overall length and weighing just 1.6 ounces, the unit is compact enough to fit within tight under‑carriage spaces yet robust enough to handle the thermal stresses generated by high‑performance engines. The converter does not require an external O₂ sensor, simplifying installation and reducing potential points of failure. With a painted exterior finish, the unit blends seamlessly with the surrounding exhaust components, preserving the aesthetic integrity of the vehicle’s under‑carriage.

Usage

This catalytic converter is suitable for a broad spectrum of passenger cars, light trucks, and performance vehicles that demand reliable emissions control without sacrificing power output. Whether the vehicle is used for daily commuting, weekend road trips, or high‑performance track days, the MagnaFlow converter delivers consistent performance by maintaining optimal exhaust temperatures and ensuring efficient conversion of carbon monoxide, hydrocarbons, and nitrogen oxides.

Installation is recommended for professional mechanics or experienced DIY enthusiasts who have access to proper welding equipment and torque specifications. Because the unit is a universal fit, some trimming or fabrication may be required to match specific exhaust pipe dimensions. The converter’s design accommodates a range of exhaust system configurations, making it an ideal choice for owners looking to upgrade from a factory‑installed converter or replace a failed unit with a high‑quality, CARB‑compliant alternative.
