Which exhaust system gives the most HP?

With a proper exhaust system, your vehicle can perform better and gain a substantial amount of horsepower. It also guarantees increased torque, less noise, and a remarkable improvement in fuel economy.

But all that can only happen if you know which exhaust system can provide you with the most benefits. So, read on to find out which exhaust systems can provide the most HP for your vehicle.

Exhaust System That Has Fewer Restrictions

Exhaust pipes that are wide and unrestricted can flow the gases out more efficiently.

But many manufacturers, to produce cheaper products, may sometimes produce bent pipes. And this can reduce the diameter and can result in the waste to get stuck.

As a result, the waste gases build up and create back pressure. A better way of bending is to insert a steel rod inside the pipe that protects the diameter of the pipe. It's called mandrel bending, and it helps the gas get out of the vehicle more smoothly.

Exhaust System That Grants Improved Scavenging

Restriction-free pipes ensure proper discharge of waste gases, and also, they create a vacuum that pulls exhaust out of every cylinder and makes sure more oxygen flow reaches the cylinders.

This is a process that continues by itself, improving vehicle performance.

Exhaust System That Has More Increased Diameter

Small exhaust pipes generally have two lanes, which can negatively impact the exhaust flow. Exhaust systems with more lanes and those with more room are more efficient in exhausting the waste gases.

How do I choose an exhaust system?

Choosing the right exhaust system depends on a few factors:

Exhaust Type

Namely, there are three main types of exhausts: header-back, axle-back, and cat-back.

Header-back exhaust type is the most expensive sort which replaces everything from all things from the header collector to the tailpipes.

Doing so, they ensure enlarged diameter. But their installation process can be challenging.

Axle-back is a budget-friendly system that comprises of the components from the front axle to exhaust tip. They are easy to install, and you can get the exhaust sound you desire.

The cat-back exhaust system is the most popular type which replaces components starting from the catalytic converter back.

It comes with relatively few modifications and can increase the exhaust flow and increase HP as a result.

Single vs. Dual Configuration

Single exhausts are made of a single set of exhaust units. They are lightweight with roomier pipe diameters.

They're also less expensive. Dual exhausts have a fashionable look, and they come with double components. It has higher flow capabilities. 

Material Type: Stainless vs. Mild Steel

Mild steel materials are not expensive but are more likely to get rusty. On the other hand, steel with aluminum coating last longer but can be more expensive.

The stainless steel exhaust system is resistant to rust, but they are more expensive, and they can be tough to work with as they can give a hard time to bend.

How can I improve my exhaust sound?

Improving the exhaust sound means increasing the sound when your car exhausts.

Having a better exhaust sound shows that your engine is powerful. There are a few ways exhaust sound can be improved.

Muffler Replacement

The mufflers that are installed originally by the manufacturers are designed in a way to mask and absorb sound. So to have a better sound output, you will have to have your mufflers replaced.

Exhaust Tip Installation or Replacement

Different types of exhaust tips are available in the market, and the tips that have larger diameters or dual walls work better to improve exhaust sound.

Exhaust Pipe's Diameter Enlargement

Having wider pipes makes it easier for the sound to get out as it faces lesser obstacles on the way. 

Is a true dual exhaust better?

There are many semis or fake dual exhaust systems in the market that do not provide the benefits a true dual exhaust system is supposed to.

A true dual exhaust system typically uses exhaust headers, catalytic converters, mufflers, tailpipes, all in doubles.

And a true dual exhaust system can come with many benefits. For example, it grants the chance to customize exhaust sound, and they are quick to spring into action when it comes to emptying the cylinders.

It allows the engine to breathe and allows the engine to have more horsepower.

What does cat-back mean?

A cat-back exhaust system is the part of the exhaust system after the final catalytic converter. The primary job of it is to ensure that the exhaust gas flows freely.

And the cat-back exhaust system has many benefits latched to it. For example, with an aftermarket cat-back exhaust system, you can get a more breathable engine, which will eventually give it more torque and horsepower.

It also is a great option if you are looking for ways to increase the fuel economy. A cat-back exhaust also produces better exhaust sounds.

Main parts of a Jeep Wrangler jk Exhaust System

It is important to know the main parts of a Wrangler jk Exhaust System in order to understand how it works.

Keeping these components in good condition will ensure that all gasses created when the fuel is burned in the combustion chamber are carried away.

The main components of an exhaust system of a jeep include exhaust manifold, catalytic converter, oxygen sensor, resonator, muffler, and exhaust pipe.

Exhaust manifold

This is one of the most important components of a jeep exhaust system.

It moves engine gases and heat into the exhaust system.

It connects to each engine cylinders head and takes their exhaust gases plus heat.

It is worth noting that it is the part of an exhaust system that is attached directly to the engine block.

It is therefore made of strong materials to withstand high temperatures from gas made in the combustion chamber of an engine.

A lot of engine power is generated in a jeep hence it requires an efficient exhaust system with wider tailpipes to handle a large number of exhaust gases.

These gases are collected into 1 pipe.

Catalytic Converter

This is also one of the vital components of an exhaust system.

It converts harmful gases such as carbon monoxide to carbon dioxide and water vapor.

It will reduce pollutants from the exhaust making your jeep safe for you and environment-friendly.

Oxygen Sensor

All modern vehicles including jeeps must have an oxygen sensor.

Oxygen sensor senses how much oxygen is in your exhaust and sends it to the computer of your car.

Depending on the information obtained, your computer will subtract or add fuel in order to achieve maximum fuel economy.

Muffler and Resonator

Muffler and resonator are the components in the exhaust system that keeps your jeep running quietly.

Combustion is a series of small explosions that will create noise.

The muffler will quiet the sound emitted from the engine when it is in use.

It has features that will absorb sound and prevent it from escaping.

They include resonating chambers, fiberglass insulation, and stainless scribble.

Exhaust Pipe

Exhaust pipes are the components that carry gasses from the manifold to the tailpipe.

They are usually made of stainless steel and can be bent or straight.

How The Best Sounding Jeep Wrangler Exhaust System Works

The best sounding jeep wrangler exhaust is comprised of many parts mainly pipes in different shapes.

They are all connected to each other and are responsible for moving the exhaust gases to the tailpipe.

It is important to understand how the system works in the order in order to keep it in good working condition.

Your jeep wrangler exhaust system has 4 main functions;

to improve the performance of your engine, to control noise,

to lessen fuel consumption and direct exhaust fumes away from you and your passengers.

The combustion chamber of an engine will produce gasses, some which are harmful such as nitrogen monoxide, carbon monoxide, and nitrogen oxide.

All these gases will be collected by the exhaust manifold each cylinder head in the engine.

They will be released through a single opening and channeled to a catalytic converter which will convert the harmful gases to carbon dioxide and water vapor.

Then the converted gases will pass through a muffler where sound will be absorbed.

The best sounding jeep wrangler exhaust system is designed to reduce noise levels.

It contains a set of tubes that are designed to absorb sound produced by the engine.

The tubes can corrode over time and this will create a hole.

No matter how small a hole is, the sound will escape through it making a lot of noise in the process.

Finally, the gasses exit via the tailpipe which is located at the back of your jeep.

It is worth noting that the entire system is connected with other components such as flanges, clamps, gaskets, and hangers.

Frequently Asked Questions About Jeep Exhaust Systems

1. What are the most common problems with Jeep exhaust system?

Answer: The worst enemy of any exhaust system is rust or corrosion.

Water vapor present as a byproduct of catalytic converter reacts with metal forming rust.

In order to avoid rusting away from the pipes, consider buying an exhaust system made of stainless steel that does not rust.

Mufflers do rust and even form a hole.

This will permeate noise to come out which is usually loud.

The first noticeable sign of an exhaust leak is increased engine noise.

If there are holes formed as a result of rust, not only will engine noise increase but toxic fumes will enter the passenger cabin.

An oxygen sensor may fail and cause it to read less accurate. Have you noticed a decrease in your gas mileage?

This could be your oxygen sensor wearing out.

A faulty oxygen sensor eventually causes your engine to burn more fuel than is needed.

You can know the oxygen sensor of your exhaust system is failing when the engine light comes on.

I would recommend that you change the oxygen sensor every 60,000 miles just save yourself from spending too much money on fuel.

A clogged muffler is a common problem especially to jeeps that often rides on rough roads.

While driving on these roads, small internal parts can come off clogging the muffler.

Reasons To Replace Your Jeep JK Exhaust System

Your car’s exhaust system is vital to its performance and longevity.

It’s one of the hardest working parts of any vehicle, responsible for removing fumes, controlling vehicle noise, improving and enhancing the overall performance of the motor and controlling fuel consumption.

A vehicle’s exhaust is a vast system comprised of many working parts including the manifold, catalytic converter, silencer and lastly the exhaust pipe.

Every one of these components must be fully working in order for the whole system to run smoothly and efficiently.

Most modern vehicle exhausts are designed to have maximum longevity for the car by being made from chrome or stainless steel.

Those exhausts made from other lesser hard-wearing materials will perhaps last for about five years – this is due to the exhaust pipe being exposed to the elements causing damage which can compromise its performance.

The modern Jeep JK (Wrangler) has a high-performance exhaust system as standard, however, there are still a number of reasons why it can greatly benefit the whole vehicle, as well as your driving experience, to replace or upgrade the exhaust:

  • The first, most obvious reason is if the original exhaust system breaks down or wears out. Older Jeeps JK models often had older, less durable exhaust components and frequently this resulted. Replacing this older style exhaust with a high-quality stainless steel (or equivalent) system will ensure you lengthen the running of the vehicle.
  • Upgrading your exhaust system to include components of the open air intake will help boost torque and volume of horsepower this will allow you to gain engine power.
  • If a new exhaust system doesn’t greatly increase your power, an expert exhaust system with a non-restrictive silencer can definitely cut down on the pressure produced, this will relieve the strain on the whole engine while the jeep is running, it also allows the heat produced by the engine to cool more rapidly.
  • Those who use their Jeep JK vehicles for off-road applications, such as climbing hills and mountains, driving through rough sand and mud, or rock crawling would agree that an upgraded exhaust system can improve a Jeep’s torque, this is an improvement widely appreciated for the adventurous driver.

When upgrading to a modified, specialty Jeep exhaust system there are a number of options that can be considered. The main options would be axle-back systems, cat-back systems or headers.

An axle-back exhaust is the most affordable option, but this doesn’t mean you are cutting back on the quality of sound or style.

It will produce the aggressive sound many looks for in a new upgraded exhaust as well as being eye-catching.

They will replace the whole exhaust system and the installation is easily done too – an added bonus!

The next, a cat-back system, will do much the same as the axle-back but it will also produce better performance for the vehicle due to its high efficiency.

They can be more expensive than the axle-back option, however, the price will be worth it while testing out the power of the vehicle on your next off-road driving adventure.

Lastly, installing a new header on its own, although not the usual option, can provide great benefits to your Jeep JK.

A new header will increase the flow rate of the exhaust – this is ideal to generously improve the power and strength of the vehicle which is what the hardcore Jeep driver will ultimately want.

Although these new headers can be costly and difficult to install yourself, they are often found to be worth it in the long run due to the positives on the running ability of the Jeep.
