The MagnaFlow Touring Series cat-back for 2008–2013 BMW M3 4.0L replaces the exhaust from the catalytic converter back with mandrel-bent 2.5in piping and two straight-through mufflers, terminating in a quad rear exit with 3.5in polished tips. It delivers a powerful, resonant tone with moderate exterior and mild interior sound, uses corrosion-resistant stainless steel, and is developed for direct-fit installation using 3D scan data, backed by MagnaFlow construction warranty.
