Description
The Flowmaster Flow FX Extreme 3.0" Stainless Steel Cat-Back Exhaust System is designed to fit the 2007-2021 Toyota Tundra with the 4.7L or 5.7L engine. Featuring a FlowFX series muffler, this system delivers an aggressive to moderate sound while boosting performance. The 3.0-inch mandrel-bent 409 stainless steel tubing maximizes exhaust flow and durability, ensuring both power and longevity. Its dump exit design eliminates the over-axle tailpipe, providing better ground clearance and departure angle—ideal for extreme off-roading. The system boasts dyno gains of 5 horsepower and 6 lb-ft of torque, improving overall vehicle performance. Factory hanger locations make for an easy at-home installation, and Flowmaster backs this product with a Lifetime Limited Warranty.
