Description
The Flowmaster Flow FX Extreme 3.0" Stainless Steel Cat-Back Exhaust System is designed for the 2003-2024 Toyota 4Runner equipped with the 4.0-liter engine. This high-performance exhaust system uses the Flow FX series muffler, providing an aggressive to moderate sound while enhancing your vehicle's performance. The system is constructed with 3.0-inch mandrel bent 409 stainless steel tubing, which maximizes exhaust flow and ensures durability, making it ideal for off-road enthusiasts. The turndown-style dump exit eliminates the over-axle tailpipe, improving ground clearance and departure angle, perfect for tackling extreme off-road conditions. This system delivers dyno gains of 4 horsepower and 5 lb-ft of torque at the rear wheels. Installation is made easy with factory hanger locations, and all necessary hardware is included. Plus, it comes backed by Flowmaster’s Lifetime Limited Warranty.
