MagnaFlow 16665 Street Series Stainless Cat-Back Performance Exhaust System

The MagnaFlow 16665 Street Series Cat-Back Performance Exhaust System is a complete stainless steel cat-back exhaust upgrade engineered to deliver MagnaFlow's signature resonant, deep exhaust tone with dyno-proven performance gains in horsepower and torque.

Key Features:

• 2.5-inch mandrel-bent stainless steel tubing for unrestricted exhaust flow and maximum performance
• Dual straight-through mufflers tuned for moderate exterior and mild interior sound levels
• Single passenger-side rear exit with a 3.5-inch polished double-wall, angle-cut rolled-edge stainless steel tip
• 100% stainless steel construction — corrosion-resistant and built to last the life of your vehicle
• Direct-fit design developed using extensive 3D scanning for OEM-like fitment and straightforward bolt-on installation
• CNC precision robotic manufacturing for consistent quality and reliable performance
• All hardware included — clamps, hangers, and mounting hardware for a complete DIY installation
• Made in the USA

MagnaFlow's cat-back layout replaces stock exhaust components from behind the catalytic converters to the exhaust tips, improving exhaust gas flow and evacuation for real-world performance gains. The Street Series is dyno-tested to verify power improvements and tuned to produce a smooth, deep tone without excessive interior drone.

System 16665 is backed by MagnaFlow's limited lifetime construction warranty and a 1-year limited finish warranty, giving you confidence in your investment for the long haul.
