The MagnaFlow Street Series Cat-Back Performance Exhaust System 16638 brings out the personality of your 1.8L 1999–2005 Mazda Miata with MagnaFlow’s signature deep, resonant, and powerful exhaust tone combined with dyno-proven performance. Designed to enhance both sound and appearance, this system adds a sporty edge that perfectly complements the Miata’s lightweight, driver-focused nature.
Fast-flowing, mandrel bent 2.5-inch main piping routes exhaust gases through a straight-through muffler before exiting via a single straight passenger-side rear outlet. The system is finished with a 4-inch polished, welded-on double wall angle-cut folded edge tip for a clean and aggressive look.
This exhaust system delivers moderate exterior sound levels and mild interior sound levels, creating an engaging yet comfortable driving experience. Featuring a cat-back layout, system 16638 replaces your vehicle’s exhaust components from near the catalytic converter on back. Extensive 3D scanning during development ensures a precise direct-fit design for easy do-it-yourself installation. Manufactured using CNC precision robotic techniques, this system is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
