Exhaust System - Overland Series - Cat-Back - Single Rear Exit - 2.5 in Diameter - Stainless - Toyota Midsize SUV 2003-09 - Kit

MagnaFlow 05-09 Toyota 4Runner V8 4.7L / 17-21 Lexus GX460 Overland Series Cat-Back Exhaust

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.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
