The MagnaFlow OEM Grade Direct-Fit Catalytic Converter 49918 is designed to replace the original converter and help keep the check engine light off while meeting Federal/EPA emissions requirements. Its free-flowing mandrel-bent tubing and corrosion-resistant stainless steel construction support durability and efficient exhaust flow. The spun-body design replicates the original equipment, while a single laser fusion weld helps reduce the possibility of leaks. A compact, low-mass construction promotes greater thermal efficiency. MagnaFlow uses 3D scanning during development to help ensure the converter fits and functions like the original equipment.
Designed for the 2004–2009 Audi S4, this direct-fit replacement is listed for the 4.2L application in the product title. It interchanges with OE part numbers 8E0 254 554 QX and 8E0 254 551 QX. Installation can be completed with proper tools and requires no cutting or welding. The converter is intended for OBDII federally registered vehicles equipped with California or Federal/EPA emissions systems, and is designed to meet or exceed Federal emissions requirements set by the EPA.
