The MagnaFlow 2010–2024 Toyota 4Runner Street Series Cat-Back Performance Exhaust System 15145 enhances the personality of your 4.0L Toyota 4Runner with MagnaFlow’s signature deep, resonant engine tone and dyno-proven performance.
Its fast-flowing 2.5-inch mandrel-bent main piping channels exhaust gases through a straight-through muffler before exiting through a Single Straight Passenger Side Rear configuration. The system is finished with 4-inch polished welded-on double wall angle cut rolled edge tips, delivering a sporty and refined appearance.
With this system installed, your 4Runner will produce moderate exterior and mild interior sound levels, offering a balanced exhaust character that enhances presence without compromising everyday comfort.
Exhaust kit 15145 features a cat-back layout that replaces your vehicle’s factory exhaust components from near the catalytic converter on back. Extensive 3D scanning during development ensures a precise direct-fit design for straightforward installation. Manufactured from durable, corrosion-resistant stainless steel using CNC precision robotic techniques, this system is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
