The MagnaFlow Street Series cat-back for 2010–2013 Mazdaspeed3 2.3L is a direct-fit stainless steel system designed to replace stock components from near the catalytic converter back. It uses mandrel-bent 3" piping, straight-through mufflers and dual split rear 4" polished double-wall tips to produce MagnaFlow's resonant, dyno-proven tone at moderate exterior and mild interior sound levels.
