Toyota Tundra owners are always looking for ways to improve the looks, performance, and/or sound of their trucks. In our opinion, one of the easiest and most affordable upgrades is a new exhaust system. In this article, we’ll be looking into the best exhaust systems for Toyota Tundra. We’ll also discuss the many types of Tundra exhaust systems along with the variances in sound, performance, and price.
The Tundra is Toyota’s weapon of choice in the hotly-contested and hugely-profitable light truck segment. It has the size, towing capacity, and standard V8 engine to make it worthy of praise against other frontrunners like the Ford F-Series and Chevy Silverado. The Toyota Tundra is also a great off-roader. The standard model has rear-wheel drive with an automatic limited-slip differential while part-time 4WD with an electronic transfer case and Auto LSD is optional.
While exhaust systems are one of the most overlooked components in a vehicle, installing a nice exhaust upgrade is enough to yield dividends in terms of acceleration, sound, and throttle response. But the big question remains: Is a Tundra exhaust kit worth the extra price over a stock OEM exhaust unit?

OEM vs. Aftermarket exhaust: Which is the best choice for my Toyota Tundra?
The stock exhaust system in any car is engineered to achieve maximum fuel economy and silent operation. Unless we’re talking about high-performance sports sedans or hot hatchbacks, modern vehicles are equipped with silent exhaust systems straight from the factory, and there’s a reason for this.
Not all car buyers are huge fans of loud exhausts. And in this world where larger SUVs, crossovers, and pickup trucks are lording it over compact cars and midsize sedans, louder exhausts are usually reserved for high-performance variants of particular German, American, or Japanese SUV, and these types of vehicles are more expensive than stock.
If you prefer the smooth and silent operation of the stock exhaust in your Tundra, upgrading to bigger and louder exhausts should be the last thing on your mind. But if you’re looking to improve power without the desire for a louder engine, upgrading to an aftermarket air filter of cold air intake is a better choice.
However, if you’re the type of Tundra owner who’s looking to increase horsepower, acceleration, and engine sound but is not prepared to shed money on expensive go-fast engine mods, upgrading to an aftermarket exhaust kit is a wise investment.
What are the types of aftermarket exhaust kits?
There are three basic types of aftermarket exhaust systems for the Toyota Tundra: Axle-back, cat-back, and header-back or turbo-back.
Axle-back exhaust kit
Perhaps the most basic, most affordable, and easiest to install among all exhaust types is the axle-back. In a typical axle-back exhaust kit, it includes all the components from the rear axle to the exhaust tip. Although it doesn’t provide massive power gains, choosing a well-designed axle-back exhaust will yield noticeable improvements in exhaust sound, acceleration, and engine pick-up.
And since an axle-back unit is easier to install, you can finish the job in your garage using a basic set of hand tools. Additionally, if all you want is a louder and more aggressive exhaust bark, axle-backs are a more economical solution as well.
Cat-back exhaust kit
Compared to an axle-back exhaust, cat-backs are designed to replace everything from the tail of the catalytic converter to the tailpipes. A typical cat-back exhaust kit includes a muffler, tailpipe, and larger-diameter piping. Depending on the configuration, cat-back exhausts are classified as X-pipe, H-pipe, or Y-pipe.
With more components in each kit, cat-back exhaust kits are more expensive and harder to install. But then again, cat-backs can yield higher gains in exhaust sound and performance. In short, cat-backs are louder than axle-backs and can squeeze out more performance from the engine.
Header-back exhaust kit
Header-back exhaust kits are engineered to replace the entire exhaust system in your vehicle, starting from the headers to the tailpipes. Depending on the type of vehicle, header-backs can also include a combination of either headers, crossover pipes, intermediate pipes, catalytic converters, mufflers, and tailpipes.
However, header-back or turbo-back exhaust kits are costlier than a typical cat-back or axle-back exhaust kit. Header-backs or full-exhausts are also harder to install. In some cases, professional installation is highly recommended since you’ll be replacing the headers altogether.
What are the benefits of an aftermarket exhaust kit?
There are two main benefits: sound and performance. But if you want to be specific, aftermarket exhaust kits are constructed using better materials and modern manufacturing techniques. Aftermarket exhausts have larger diameter tubing to improve the exhaust flow. It also reduces harmful engine backpressure under heavy loads, basically allowing the motor to breathe better.
In order to get a better understanding of how this works, hold your breath, pinch our nose slightly, and try to exhale through your nose. On the other hand, upgrading the exhaust system is like breathing with no restrictions. Aftermarket exhaust kits are designed to do the same by allowing the engine to breathe easier while giving you a nice, rumbling exhaust sound.
Choosing a Toyota Tundra exhaust: Stainless steel or aluminized steel?
In terms of quality and longevity, stainless steel exhaust kits are your best bet. Stainless is engineered to resist corrosion and oxidation like an ordinary steel exhaust. However, stainless steel exhaust kits are more expensive than other varieties.
On the other hand, aluminized steel is crafted from ordinary non-stainless steel but is coated with aluminum-silicon alloy to give it the finish of genuine stainless steel. The protective coating forms a strong bond with the base material to provide better protection against rust and corrosion.
And even though aluminized steel is more affordable than stainless steel exhausts, the aluminum coating can scrape off of chip away by scrapes, heavy impacts, and rock hits. And when this happens, it’s easier for rust and corrosion to penetrate the base metal, unlike pure stainless steel.
In some cases, cat-back or axle-back exhaust systems are sold in both aluminized and stainless steel options. However, the stainless variant is usually a hundred or more dollars expensive than aluminized steel.
Mandrel-bent versus Crush bend exhaust tubing: Which is better?
The factory OEM exhaust in your Toyota Tundra is equipped with crush bend piping. Although this method is fast, easy, and more affordable, the pipe bends create performance-robbing restrictions that affect the engine’s performance.
This is the reason why aftermarket exhaust kits have mandrel bent pipes. This means the exhaust pipes are bent using a flexible rod that prevents the pipe walls from creating kinks in the assembly. This also means the piping maintains a consistent diameter in the bent areas, thereby allowing the exhaust to flow freely.
