Flowmaster Outlaw Extreme High Clearance Exhaust for 2003-2024 Toyota 4Runner - 817961

The Flowmaster Outlaw Extreme Cat-Back Exhaust System, part number 817961, is designed for 2003-2024 Toyota 4Runner models equipped with the 4.0L engine. Built from durable 409 stainless steel, this high-clearance performance exhaust features 3-inch 16-gauge mandrel-bent tubing and a compact Outlaw Series muffler for a deep, aggressive exhaust tone. The single dump-style turndown exits immediately after the muffler, eliminating the conventional over-axle tailpipe to improve ground clearance and departure angle for demanding off-road use.
