What is exhaust wrap, and why is it used?
For most people, the biggest win with exhaust wrap is not chasing a huge power figure. It controls where heat goes.
On many modified cars, the manifold, downpipe or screamer pipe sits much closer to wiring, coolant hoses, brake lines, intake pipework and body panels than the factory setup ever did.
That means radiant heat becomes a real problem, especially on turbo cars, track cars and drift builds. Exhaust wrap helps keep that heat inside the pipework, which makes the whole engine bay easier to manage.
Exhaust wrap, also known as exhaust wrap tape or exhaust heat wrap, is a specialised material designed to insulate and protect a vehicle's exhaust system. It is typically made from fibreglass, ceramic, or titanium and is wrapped around the exhaust pipes and headers.
The primary purpose of exhaust wrap is to manage heat by containing it within the exhaust system, preventing it from radiating into the engine bay or other sensitive components.
One of the main reasons why exhaust wrap is used is to improve performance. By reducing the heat that escapes from the exhaust system, the wrap helps to increase the scavenging effect, which is the process of removing exhaust gases from the combustion chamber.
This, in turn, improves the flow of exhaust gases, leading to slightly increased horsepower and torque. Additionally, by keeping heat away from sensitive components, exhaust wrap can also help to prevent heat-related damage and extend the lifespan of the exhaust system.
Benefits of using an exhaust wrap
Using an exhaust wrap on your vehicle can offer a wide range of benefits. Let's take a closer look at some of the key advantages.
Reduced heat damage
Excessive heat can cause significant damage to various components of your vehicle, including the engine, wiring, and surrounding parts. Using an exhaust wrap, you can effectively reduce the amount of heat radiated into these areas, minimising the risk of heat-related damage and extending the lifespan of your vehicle's components.
We often see this, especially with high-powered cars with aftermarket systems, where the manifolds or downpipes are much closer to engine bay components than the stock systems. Also, the exhaust systems get hotter than the factory ones due to increased power.
Increased horsepower and torque
Exhaust wrap helps to improve the flow of exhaust gases by keeping heat within the exhaust system. This increases the efficiency of the scavenging effect, resulting in a slight bump in horsepower and torque output for your vehicle.
Another benefit would be the lower intake air temperature, or IAT for short.
The cooler the air going into the engine, the more power you will have. Exhaust wrap can make a noticeable difference if you want a slight performance boost or to maximise your vehicle's potential on the track.
It is worth keeping expectations realistic here.
Exhaust wrap is not a magic power mod on its own. The real benefit is improved heat control, which can help the rest of the setup work better.
Lower engine bay temperatures can help protect intake temperatures, reduce heat soak and keep nearby parts happier, which is especially useful on turbo builds that are already fighting for cool air.
Improved fuel efficiency
If heat escapes from your vehicle's exhaust system, it can cause the air around it to heat. This decreases air density, negatively affecting your vehicle's performance and fuel efficiency.
To prevent this, you can use an exhaust wrap to keep the heat within the system. By doing so, you can maintain optimal air density, which leads to improved fuel combustion and better fuel efficiency.
Minimised heat soak
Heat soak occurs when the engine and surrounding components absorb heat from the exhaust system, even when the vehicle is not in motion.
This can lead to increased engine bay temperatures and negatively impact performance. Using an exhaust wrap, you can prevent heat soaking and keep your engine bay temperatures more manageable.
Reduced engine bay temperatures
Excessive heat in the engine bay can not only cause damage to components but also create an uncomfortable driving experience.
By containing heat within the exhaust system, exhaust wrap helps to reduce engine bay temperatures, making your driving experience more enjoyable, especially in hot climates.
Enhanced sound insulation
In addition to its heat-containment properties, exhaust wrap acts as a sound insulator. Reducing the transmission of sound waves can help minimise exhaust noise, resulting in a slightly quieter and more refined driving experience.
These are just a few of the many benefits that an exhaust wrap can offer. From improving performance and fuel efficiency to reducing heat damage and minimising noise, it's clear that incorporating exhaust wrap into your vehicle's exhaust system can significantly impact its overall performance and longevity.
How to choose the right exhaust wrap for your car
To select the suitable exhaust wrap for your car, consider these factors: you can choose a wrap that suits your vehicle's specific needs and requirements. Here are some key considerations to keep in mind.
Temperature resistance
Ensure that the exhaust wraps you choose can withstand the temperature range your vehicle's exhaust system produces. Different materials have different heat resistance capabilities, so selecting a wrap that can handle the temperatures your exhaust system is likely to reach is essential.
Most road and track cars will never see temperatures anywhere near the limit of a quality wrap, but you still want a product with a strong safety margin.
Our Exoracing Titanium or Carbon Exhaust Wrap is rated to 980°C continuous and 1350°C intermittent, which is more than enough for the vast majority of performance applications.
This is more than most cars would produce, making it viable for most applications.
Durability
Consider the durability of the exhaust wrap material. It should withstand daily use and exposure to harsh conditions without deteriorating or losing its insulating properties. Look for wraps known for their long-lasting durability to ensure a reliable and effective solution.
To test our line of Exoracing exhaust wrap, we have drivers such as Martin Wonnacott, who runs an 800bhp Toyota Chaser professional drift car. Being driven on the absolute limit all the time is an excellent testament to how well our exhaust wrap holds up to the abuse.
Ease of installation
Some exhaust wrap materials are easier to install than others.
If you are a beginner, the easiest place to start is usually the manifold and the first section of downpipe, as these areas tend to throw the most heat into the bay.
Take your time, keep the overlap consistent, and do not leave loose sections. A neat and tight install usually performs better and lasts longer than a rushed one.
This will help ensure a successful and hassle-free installation process. If you want to learn how to install exhaust wrap, skip to the next section.
Aesthetics
While the primary purpose of exhaust wrap is to enhance performance, aesthetics can also play a role in your decision. Consider the appearance of the wrap and how it will complement your vehicle's overall look.
Some wraps come in different colours and finishes, such as black carbon or titanium exhaust wrap, allowing you to customise your exhaust system's look. While going down this route, running a matching heat management setup, such as a turbo blanket or wastegate blanket, may be worth using to reduce engine bay temperatures further.
Budget
Lastly, consider your budget when choosing an exhaust wrap. Different materials and brands come at varying prices, so finding a wrap that fits your budget without compromising quality or performance is essential.
Remember that investing in a high-quality wrap can save you money in the long run by preventing heat-related damage and extending the lifespan of your exhaust system.
How to install exhaust wrap
Installing exhaust wrap requires careful attention to detail and following the correct procedure. While the specific steps may vary depending on the type of wrap and your vehicle's exhaust system, the following general guidelines will help you successfully install exhaust wrap.
Since writing this article, we have now fully expanded this section with a video installation, which I will add below, and a full article on how to install exhaust wrap.
1. Prepare the exhaust
Start by removing any obstacles or components that may hinder the installation process, such as heat shields, brackets, or sensors. Ensure that the exhaust system is cool to the touch before proceeding.
2. Clean the exhaust system
Thoroughly clean the exhaust pipes and headers to remove any dirt, grease, or debris. This will ensure proper adhesion of the wrap and prevent any contaminants from compromising its performance.
3. Measure and cut the wrap
Measure the length of the exhaust pipes and headers, and cut the wrap accordingly. It's recommended to use a pair of sharp scissors for a clean cut. Leave some overlap to secure the wrap in place.
4. Wet the wrap
Before applying the wrap, dampen it with water to make it more pliable and easier to work with. This will also help activate the adhesive properties of certain wraps. Having a spray bottle here is a very good option, as if it starts to dry out, you can instantly dampen it.
5. Start wrapping
Begin wrapping the exhaust pipes or manifold, starting from the end opposite the engine. Maintain a consistent overlap and tension throughout the process to ensure a tight and secure fit.
6. Secure the wrap
Use stainless steel cable ties or wire to secure the wrap in place. Start at one end and work your way towards the other end, ensuring that the wrap is held securely in position. Trim any excess wrap if necessary.
7. Repeat the process
Repeat the wrapping process for each exhaust pipe or header, following the same steps. Take your time to ensure a neat and uniform appearance.
8. Allow the wrap to cure
After the wrap is installed, allow it to cure according to the manufacturer's recommendations. This typically involves running the engine at idle for a certain period to allow the wrap to fully adhere and form a tight seal.
Remember to consult the manufacturer's instructions and guidelines specific to the exhaust wrap you are using. Proper installation is crucial to ensure optimal performance and longevity of the wrap.

Tips for installing exhaust wrap effectively
While the installation process may seem straightforward, some additional tips and tricks can help you achieve the best results when installing exhaust wrap. Take a look through these tips to ensure an effective and professional-looking installation:
Watch out for sharp edges
Be cautious of any sharp edges on your exhaust system, as they can potentially damage the wrap during installation. Consider using protective tape or heat-resistant sleeves to cover sharp edges and ensure a smooth wrapping process.
Wear protective gear
When handling exhaust wrap, it's advisable to wear gloves and eye protection to prevent any skin irritation or injury. Some wraps may also produce fine particles or fibres, so wearing a dust mask is recommended. We've installed exhaust wrap hundreds of times, and you really don't want the fibres on your skin, trust me!
Overlap consistently
Maintain a consistent overlap when wrapping the exhaust system to achieve a professional finish. This will also help prevent any gaps or areas of the exhaust system from being left exposed.
Prevent wrap slippage
To prevent the wrap from slipping or unravelling, use stainless steel cable ties or stainless steel wire at regular intervals along the length of the exhaust system. This will help hold the wrap securely in place and maintain its tension.
Allow for expansion
Leave a small gap between the wrap and any nearby components, such as sensors or heat shields, to allow for expansion and prevent potential damage. Consult the manufacturer's recommendations for the specific wrap you are using.
Inspect for tightness
After the wrap has cured, check for any loose or sagging areas. Tighten the stainless steel cable ties or wire as needed to ensure a tight and secure fit.
Following these tips will help you achieve a professional and effective installation of exhaust wrap, maximising its performance and benefits.
