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.
Material
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 817692
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.
Features:
- Material: 409S Stainless Steel
- Exhaust style: Cat-Back with mandrel bends
- For vehicles: 2009-2018 Tundra Pickup 4.6L/5.7L

- Black ceramic tips

Genuine Toyota Parts PTR03-34101
Conventional wisdom says there’s no better replacement part than the one made by your vehicle manufacturer. There’s something to be said for that, and this Genuine Toyota Cat-Back Exhaust is the proof of it. For a replacement exhaust that’s guaranteed not to void your warranty, the Genuine Toyota exhaust is a winner.
Another advantage of a Toyota exhaust is that you know what to expect. The performance and sound will be identical to what the truck could do fresh from the factory. If you’re looking more for an exact replacement than an upgrade or change, this is the best way to go.
Construction quality and durability are also strong points of the Toyota Cat-Back exhaust. The stainless steel won’t rust or degrade, and the fit of the components is on point. The only problem is you don’t get everything you need in this kit. You’ll have to buy the tailpipe separately, as well as any gaskets and bolts you need to put it on. Keep this in mind when you’re planning your budget or it’ll be a much costlier install than you were expecting.
