MagnaFlow HM Grade spun-body direct-fit catalytic converter for 2002-2004 Audi A4, including Quattro applications. It mirrors the OE spun-body layout to help keep the check engine light off and installs without cutting or welding. Mandrel-bent tubing and corrosion-resistant stainless construction maintain factory flow characteristics; included gasket and hardware simplify sealing and reduce leak risk.
