MagnaFlow Sport Series cat-back for 2001–2006 BMW M3 E46 3.2L uses 2.25in mandrel-bent piping, straight-through mufflers and a quad split rear exit with 3in polished double-wall tips to create an aggressive, resonant note. The system replaces the exhaust from the catalytic converter back, is designed with 3D-scanned direct-fit geometry, and is built from corrosion-resistant stainless steel with CNC production techniques.
