Model Year

Not every year of the Toyota Tundra uses the same exhaust style. Pay close attention to your vehicle’s model year before you start shopping, and use that as your guide for whether the system will fit or not. An ill-fitting exhaust can cause leaks, reduced power, and other issues, so it’s not something you want to guess at.

Exhaust Tube Construction

Most standard factory exhaust systems uses a construction style that results in crush bends. While this process is quick and easy, it narrows the pipe at the bend, imposing restrictions in the air flow and lessening your efficiency.

High-end exhaust systems use a different process called mandrel bending. In a mandrel bend, there is no loss of diameter. Systems with mandrel bends will give you improved horsepower, and also tend to have a bigger, better sound.


The exhaust system of your truck is exposed regularly to moisture, road grit, and other hazards. For long-lasting performance, you’re looking for a metal that resists rust and corrosion, and won’t be damaged by everyday driving hazards. Stainless steel is the most durable choice when it comes to aftermarket exhausts.

Flowmaster designs exhaust systems for everything from trucks to muscle cars and their Outlaw Stainless Steel Cat-Back Exhaust System is a perfect fit for Toyota Tundras made from 2009-2018. The system you’ll get here isn’t just easy to install, but will also be an improvement over the factory exhaust.

If you’re looking for an aggressive exhaust system, the Flowmaster Outlaw is your perfect match. The combination of dyno tuning and the proprietary Flowmaster muffler system give you a really powerful sound. Once you open up the throttle it absolutely roars—a bit too much for some drivers, so keep that in mind if you’d rather have a quieter exhaust system.

This Flowmaster exhaust isn’t just about sound, either. It’s well-built for maximum drive power, with mandrel bends for efficient airflow. Since it’s stainless steel, it holds up well even in extreme conditions, with no worries of it rusting over time.

Most drivers can install this exhaust on their Toyota Tundra in just 2-3 hours. The Flowmaster Outlaw assembles easily—the only tricky part for us was getting the tips on. The included clamps are a bit weak, too, and you may want to do some spot welding if you don’t want the pipes to hang. These minor quibbles aside, it’s a fantastic exhaust for drivers who want power.

  • Exhaust style: Cat-Back with mandrel bends
