The MagnaFlow HM Grade direct-fit catalytic converter for 2001–2003 Audi S8 (passenger side) is an EPA-compliant replacement designed to match OE fit and emissions function while helping prevent a check engine light. The spun-body design supports thermal efficiency. Mandrel-bent tubing and corrosion-resistant stainless steel preserve OEM-like flow. A single fusion weld reduces leak risk and the unit includes hardware to permit a straightforward installation without cutting or welding.
