The MagnaFlow Street Series cat-back exhaust for 2015–2017 GMC Terrain 3.6L is a direct-fit stainless system that replaces components from the catalytic converter back. It uses mandrel-bent 2.5in main piping and straight-through mufflers with quad-split 3in polished tips to produce MagnaFlow’s resonant tone and dyno-proven gains, offering moderate exterior and mild interior sound with easy installation.
