The MagnaFlow INFINITI Street Series 16820 brings out the personality of your 3.7L 2008-2015 INFINITI with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 2.5in. main piping and 3 Straight-Through mufflers ending in a Dual Split Rear exit with 4.5in. With polished Welded-On-Double Wall-Angle Cut-Folded Edge tips, this INFINITI exhaust kit has the performance chops to match its sporty sound and appearance. Upgrade your ride to the next level with an exhaust with pipes to shame other INFINITI’s. With this system, your vehicle will produce moderate exterior and Mild interior sound levels while leaving other cars and trucks feeling envious at every stoplight. Exhaust kit 16820 features a cat-back layout that replaces your ride’s stock exhaust components from near the catalytic converter on the back. Extensive 3D scanning during development has resulted in a direct-fit design you can easily install yourself. 16820 is produced using CNC precision robotic manufacturing techniques and is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
