MagnaFlow Overland Series Cat-Back Performance Exhaust System
#19544
The MagnaFlow Overland Series Cat-Back Performance Exhaust System #19544 for the Lexus GX470 (2003-2009), GX460 (2010-2021) and Toyota 4Runner (2003-2009) adds MagnaFlow’s signature deep tone and dyno-proven performance to your overlanding rig. The weight optimized exhaust system’s mandrel bent 2.5” tubing and single, straight-through muffler are designed to fit higher up in the undercarriage than the stock exhaust configuration. Combined with a single, high-clearance, no-tip, passenger-side exit, these features ensure improved ground clearance and utility. This MagnaFlow exhaust system was developed with versatility in mind in order to be seamlessly compatible with the most popular bolt-on aftermarket applications. Thanks to MagnaFlow’s No Drone Technology, exhaust kit #19544 is specifically engineered to bring out the natural character of your rig’s motor while minimizing the natural droning frequencies created at cruising speeds. As a result, this exhaust system is as well-mannered on long drives to overlanding locales as it is excellent at improving off-roading capability with improved ground clearance and departure angles. The durable 100% stainless steel construction and CNC precision robotic manufacturing used by MagnaFlow #19544 ensures easy bolt-on installation and seamless compatibility, all covered by MagnaFlow’s limited lifetime construction warranty.
