Toyota 4Runner Performance Exhaust - Flowmaster - Outlaw Extreme Cat-Back - 03–24. Built for the 4.0L 4Runner, this high-clearance system delivers a deep, assertive tone and off-road friendly packaging.
Flowmaster’s Outlaw Extreme uses 3.0-inch, 16-gauge mandrel-bent 409 stainless steel and an Outlaw Series muffler for durability, signature sound, and freer flow. A turndown dump exit after the muffler deletes the over-axle tailpipe to aid ground clearance and departure angle on the trail. It installs using factory hanger locations, includes all required hardware, and carries Flowmaster’s Lifetime Limited Warranty. Fits 2003–2024 Toyota 4Runner 4.0L. Flowmaster reports max dyno gains of 6 hp and 9 lb-ft at the rear wheels.
