The MagnaFlow Street Series Cat-Back Performance Exhaust System 16917 enhances the personality of your 4.3L 2002–2008 Lexus SC430 with MagnaFlow’s signature deep, resonant engine tone and dyno-proven performance. Designed to optimize exhaust flow and throttle response, this system delivers a refined yet sporty character that complements the SC430’s premium styling.
Featuring fast-flowing 2.5-inch mandrel-bent main piping and one Straight-Through muffler, this exhaust system maximizes efficiency and performance. It terminates in a Dual Split Rear exit with 3.5 x 5.5-inch polished welded-on double wall straight cut rolled edge tips, providing a bold and elegant finish.
With this system installed, your vehicle will produce Moderate exterior and Mild interior sound levels, offering a distinctive V8 tone while maintaining a comfortable cabin environment.
Exhaust kit 16917 features a cat-back layout that replaces your factory exhaust components from near the catalytic converter rearward. Extensive 3D scanning during development ensures a precise direct-fit design for easy do-it-yourself installation. Manufactured using CNC precision robotic techniques, the system is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
