Product details
The MagnaFlow® Overland Series™ Cat-Back Performance Exhaust System #19544 for the Lexus GX470 , GX460 and Toyota 4Runner 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.
