8 Best Exhaust System For Toyota Tacoma in 2021

How do exhaust systems work?

How do exhaust systems work

Before buying the best exhaust system for Toyota Tacoma, it is crucial to understand how the exhaust systems work and what is their significance. Let’s understand this in simple words:

The main function of any exhaust system installed in the vehicle is to get rid of the waste gases (generated by the fuel combustion) as quickly and efficiently as possible to protect the engine system of the vehicle and maximize its performance. Along with cleaning the emission process, the exhaust system of the vehicle is responsible for noise reduction as well. There are three harmful gases released during the fuel combustion process when the fuel gets burned by the spark plug of the vehicle and these gases are carbon monoxide, nitrogen oxide, and nitrogen monoxide. To get rid of these three gases, there are some crucial components available in the exhaust system about which we have explained below.

Components of the Exhaust System

Components of the Exhaust System

There are five major components of any exhaust system responsible for getting rid of the waste gases to improve the performance of the vehicle & engine system. Depending upon the model type and version, the layout of the modern exhaust systems may vary slightly but the overall functioning and process remains the same and is explained below:

1. Exhaust Manifolds/Header

The waste gases released after exhaust gets emitted from the cylinder head by the engine’s piston and collected by Exhaust Manifold, available onto your engine’s tip. The exhaust manifolds are connected to each cylinder via a piece of pipe. These pipes collect the waste gases from all the cylinders and then send it to a single exit pipe called collector/front pipe.

Although the stock header in the vehicles is designed to reduce the cost and space, they don’t as efficiently expel harmful gases as high-quality exhaust systems available in the market. Exhaust manifolds are generally made from the cast iron to prevent damage but you can also go for the advanced material options available in the market by brands like Doug Thorley  or Gibson to choose the best from the nickel-chrome plated mild steel or stainless steel options.

2. Catalytic Converters

Also known as Catcon or Cat Converter, Catalytic Converters are the most useful component of the exhaust systems as they help in cleaning the waste gases coming to the exhaust system by initiating a series of chemical reactions. The catalytic converter has platinum and palladium-coated ceramic beads, referring as Catalyst or Honeycomb. When harmful gases like carbon monoxide, nitrogen oxide, and nitrogen monoxide pass-through this catalyst, the series of chemical reactions convert the harmful oxides and hydrocarbons into water vapour, oxygen, nitrogen, and carbon dioxide to make exhaust gases and the environment clean and safer.

If you only want to replace the catalytic converter instead of the whole aftermarket exhaust system of your Toyota Tacoma, there are two famous brands you can rely on: TED and Evan Fischer. If you want Cat converter for Toyota Tacoma 2005-2015 model, go for TED Direct Fit Cat Converters . For old models like Toyota Tacoma 2005-2008 Front catalytic Converter, go for Evan Fischer Aftermarket Front Cat Converter set .

3. Cat-Back Exhaust System

The Cat-back Exhaust System is a kind of individual exhaust system that comes into play once the exhaust gasses are released from the Cat Converter after the chemical reaction. The “Cat-Back” term refers to the exhaust system part after the catalyst. Although Muffler and Tailpipes are the major components of the exhaust system, they come under the Cat-Back Exhaust System that works in sync to decide the efficiency of expelling the exhaust gases from the engine. So, to understand how Cat-Back Exhaust System works, we have to understand the role & working of its two main components, i.e:

1) Muffler/Silencer

As the name indicates, the main function of the muffler or silencer is to reflect the sound waves within the thin tubes to reduce the noise level produced by the engine. The silencer is designed with a high-resonating chamber finely tuned to reflect the sound waves through it to cancel out each other. It is because of the muffler or silencer that you won’t feel the heavy trembling sound of your engine. But the silencer can corrode over time and even the slightest hole in it can produce lots of unwanted noise. So it is crucial to check the material of the silencer while buying the exhaust system for Toyota Tacoma to prevent noise production.

The tail pipe is the last part of the exhaust system but is the relevant one as the diameter and bending of the pipe decide the efficiency of the exhaust system works. Most of the high-quality aluminized steel tail pipes come with chrome-finished exhaust tips. The wider will be the exhaust tips, the less pressure and effort will require to expel the exhaust gases out of the vehicle with more efficiency.

One of the performance exhaust tips brands available online is DC Sports, which comes with Universal Fitment. There are two models of DC Sports brand which you can consider for high-quality exhaust tips for Toyota Tacoma, i.e DC Sports EX-1013 Resonated Muffler  and DC Sports EX-1012B Resonated Muffler . Depending upon the material quality you like, you can choose one out of these two.

Things to Consider while buying the best exhaust system for Toyota Tacoma – Ultimate Buying Guide

There are several things to consider while buying the best exhaust system for Toyota Tacoma apart from the exhaust system type, like:

1. Purpose

The most important thing to determine first to buy the best exhaust system for Toyota Tacoma is the purpose you want to achieve with that. Every car enthusiast has their own priorities and preferences. Some want better noise reduction while others want better fuel economy. Depending upon your purpose, we have explained three types of exhaust systems available in the market to replace the stock ones.

If your main purpose is to enhance fuel economy and engine performance, then the Header-back exhaust system is the right choice for you.

So, determine your purpose first and then consider the best options under that type.

2. Performance

Another crucial factor to consider after the purpose is the type of performance you want with the aftermarket exhaust. As we explained earlier, the header-back exhaust system provides the highest engine performance while the axle back provides the least. So depending upon the level of performance you want to achieve with your exhaust system replacement, you can suit the right type for your Toyota Tacoma.

3. Price

Price is definitely a deciding factor while buying the best Toyota Tacoma exhaust system. Depending upon the level of upgradation you want, like either you want to replace or upgrade all the components of your stock exhaust system or only some of them, the cost varies. If you go for the complete upgradation from Header to exhaust tips, it will cost you more expensive than that of individual cat converter or tubing up-gradation.

4. Ease of Installation

Not every exhaust system comes with easy to install kit or guide and if you are a newbie to replace the exhaust system accessories, the process could be challenging for you to perform by yourself. So always go for the one that comes with an easy installation guide, otherwise, you have to spend some additional bucks on the professional’s assistance.

There are several best exhaust system available in the market that comes with easy to install feature. It is advisable to choose the right one amongst them to save both your time and effort.

5. Material Quality

The durability and performance of an aftermarket exhaust depend upon its material quality. To prevent the exhaust system from rust and external damage, the performance exhaust system is designed with high-quality stainless steel material. There are three grades of stainless steel material used in high-performing exhaust systems and these are:

Aluminized Steel

If you want an affordable yet safe stainless steel material quality for your exhaust system, then Aluminized steel is the most common material type used in aftermarket exhaust available in the market. In aluminized steel, the heavy-duty pipes of steel are coated with high-quality aluminum-silicon alloy to prevent the tubes/pipes from rusting or chemical damage.

409 Stainless Steel

409 stainless steel pipes are another cost-effective option available in the market that provides excellent durability, high-strength performance, and corrosion resistance for the hassle-free performance of the vehicle.

304 Stainless Steel

304 Stainless Steel material is not commonly found in exhaust systems as only the top brands use it due to its expensive price. It is considered the topmost quality stainless steel material for exhaust systems due to its high concentration of nickel and chromium. Borla exhaust system comes with 304 stainless steel material to give you the best protection against rust, damage and corrosion.

6. Climate Conditions

Climate conditions can affect the performance and the durability of your exhaust system up to some extent and thus it is crucial to keep that in mind while buying the best exhaust system for Toyota Tacoma. If you live in a dry area, there are fewer chances of rusting and corrosion & thus you can go for aluminium exhaust as well. But if you live in an area with extreme moisture conditions, rusting and corrosion are the common things that can damage your exhaust system and thus you need high-quality stainless steel anti-rust coated material for the same.

7. Pipe Design

The pipe design of the exhaust really matters as it affects the performance and the efficiency of the engine. You can understand it as follows:

In case of reduced diameter or more bending or any blockage in the exhaust pipe, exhaust gas won’t be able to release from the pipe effectively, resulting in the backpressure build-up that will send the exhaust gases back to the engine’s piston and will affect the engine’s performance. That is why it is essential to have less bending or a wider diameter to ensure the right laminar flow of the exhaust gases.

In the performance exhausts available in the market, you can find the high-tech mandrel bending technology in the exhaust pipes, where a flexible steel rod is inserted in the steel pipe to prevent it from crushing or damaging at high pressure. This high-tech mandrel-bent tubing reduces the backpressure and enhances the power and torque of the vehicle.

8. CARB Legal

If you are in California, it is advisable to go for CARB legal catalytic converters or exhaust systems. CARB stands for California Air Resources Board, ensuring the quality and performance of all the parts used in the exhaust system.
