MagnaFlow 15-17 GMC Terrain V6 3.6L 409SS Cat-Back Exhaust Quad Split Rear with 3in Polished Tips

The 3-inch polished tips on this MagnaFlow cat-back exhaust system are a strong visual cue, but the real story starts with the 409 stainless steel construction. This material is chosen for its ability to resist corrosion, meaning this system is built to last through all sorts of weather. It replaces your stock exhaust from the catalytic converter back, giving your 2015-2017 GMC Terrain with the 3.6L V6 engine a more aggressive, resonant tone without being overwhelming, with moderate exterior and mild interior sound levels.

This system uses mandrel-bent 2.5-inch piping for smooth airflow, which helps your engine breathe easier. MagnaFlow's dyno-proven design means you're not just getting a different sound; you're also getting an improved performance feel. The quad split rear exit with polished, double-wall tips gives your Terrain a distinct look that stands out. MagnaFlow uses CNC robotic manufacturing for precision, ensuring a direct fit that makes installation more straightforward.

This cat-back system is designed to bolt up to your existing exhaust hangers and connections, making it a manageable project for many DIYers. You'll get a noticeable change in your vehicle's personality, both in sound and appearance, that complements the V6 engine's capabilities. MagnaFlow backs this system with a 1-year limited finish warranty and a limited lifetime construction warranty.
