The MagnaFlow Overland Series Cat-Back Performance Exhaust System #19657 replaces the factory exhaust from the catalytic converter rearward on the 2025 Toyota 4Runner with the 2.4L L4 gasoline engine. The manufacturer describes 3-inch mandrel-bent stainless piping feeding straight-through oval and round mufflers with No Drone Technology, which uses passive quarter-wave noise cancellation to reduce highway drone. Its high-clearance, single driver-side rear exit lifts the tailpipe well above the stock outlet, which helps on rocky trails. Stock exhaust sounds flat on this inline-four, and cheaper universal mufflers rarely include drone-cancelling tuning, so this system targets both tone and cabin comfort on long drives. Searches for 2025 4Runner 2.4L cat-back, 6th gen gas 4Runner exhaust, no drone 4Runner muffler, and high clearance 4Runner exhaust point to this part.
The manufacturer lists fitment for the gas-only 2025 to 2026 4Runner and excludes hybrid engines. Owners on user forums report the exhaust sits noticeably higher than the factory unit, and one owner described a subtle, drone-free interior sound. Because the manufacturer's catalog shows differing year ranges and pipe diameters across its listings, confirm your truck's model year, trim, and engine before ordering.
No. The manufacturer states the system is designed for the L4 2.4L gasoline engine and excludes hybrid engines. Owners on user forums say the same.
The manufacturer says its No Drone Technology is designed to eliminate highway drone through passive quarter-wave noise cancellation. Owners on user forums report that drone can still appear around 1,500 to 2,000 RPM with some aftermarket systems on the 6th gen 4Runner, and results depend on grade and drive mode.
Per the manufacturer, the kit includes a gasket and clamps. The mounting bracket is not included, so check whether your existing hangers will reuse with the system.
This is a bolt-on install from the catalytic converter back, so no cutting or welding is required, according to the manufacturer. The manufacturer notes that basic automotive knowledge is needed and recommends professional installation if you are unsure. Plan for jacking and supporting the vehicle safely, soaking rusted OEM hangers and rubber insulators with penetrating lubricant, and loosely fitting the hangers before final tightening so the pipe clears the axle and the rear suspension. Owners on user forums have had the system installed at local shops, which is a reasonable option if you lack lift or hanger-removal experience. The manufacturer also publishes an installation guide, so review it before starting.
