Description
Overview
The Flowmaster Force II Cat-back Exhaust System is a complete bolt-on upgrade engineered for 2009-2021 Toyota Tundra trucks equipped with the 4.6L, 4.7L or 5.7L engine. Built for 4WD applications and covering regular cab/long bed, double cab/short bed and CrewMax configurations, this Force II system replaces your restrictive factory exhaust with mandrel-bent stainless steel tubing designed to improve flow, add power, and give your Tundra a more aggressive presence.
Manufactured from durable 409S stainless steel, the kit features a flanged dual inlet feeding 2.50-inch mandrel-bent tubing back into a proven 50 Series Big Block performance muffler. From there, the system exits into dual 2.50-inch tailpipes finished with 3.00-inch polished 304 stainless steel tips embossed with the Flowmaster name for a clean, unmistakable look.
Key Benefits
As a Force II system, this cat-back delivers improved horsepower and torque along with a moderate performance sound level both inside and outside the truck. The mandrel bends preserve exhaust diameter through every turn, while the 50 Series Big Block muffler produces a deep tone that stays refined enough for daily driving without droning.
One of the standout advantages is flexibility. The kit includes both side-exit and rear-exit tailpipes, so you can choose the exact look that suits your Tundra without buying additional components. Whichever exit you select, the polished 304 stainless tips deliver a premium finished appearance.
