CFR Exhaust Problems

CFR Exhaust Problems

When it comes to aftermarket exhaust systems, CFR has established itself as a popular choice among enthusiasts looking to improve the performance and sound of their vehicles. However, like any product, CFR exhaust systems also have their fair share of issues. In this article, we will discuss some of the common problems that owners may encounter with CFR exhaust systems, and how they can be addressed.

Excessive Noise Output

One of the most common complaints about CFR exhaust systems is the excessive noise output. While some enthusiasts enjoy the loud and aggressive sound, others prefer a more subtle and refined tone. If you find yourself in the latter group, you may be disappointed with the noise level of your CFR exhaust system.

The first step in addressing this issue is to determine whether the noise is a result of a manufacturing defect or if it is simply a characteristic of the exhaust system. If it is a defect, you may be able to contact CFR for a replacement or refund. However, if it is a characteristic of the system, you may need to consider additional modifications such as adding a resonator or a muffler to reduce the noise.

Poor Performance and Decreased Power

Another issue that some owners may experience with CFR exhaust systems is poor performance and decreased power. While the primary goal of an aftermarket exhaust system is to improve performance, it is possible for certain designs to actually hinder the flow of exhaust gases and reduce power output.

If you are experiencing a noticeable decrease in performance after installing a CFR exhaust system, it is important to first check for any leaks or blockages in the system. A leak or blockage can disrupt the flow of exhaust gases, resulting in reduced power. Additionally, you may consider consulting a professional tuner who can optimize your vehicle’s engine management system to ensure that it is properly calibrated for the new exhaust system.

Leaking Exhaust Gaskets

Leaking exhaust gaskets can be a frustrating problem for CFR exhaust system owners. These gaskets are responsible for sealing the joints between various components of the exhaust system, and if they are not installed properly or if they become damaged over time, they can result in leaks and noisy exhausts.

The first step in addressing this issue is to identify the location of the leak. This can often be done by inspecting the exhaust system for any visible signs of exhaust gas escaping. Once the leak is located, the damaged gasket can be replaced. It is important to ensure that the new gasket is installed correctly and tightened to the specified torque specifications to prevent future leaks.

Corrosion and Rusting

Another common issue with CFR exhaust systems is corrosion and rusting. This is especially true for systems that are exposed to harsh weather conditions or road salt. Over time, the metal components of the exhaust system can begin to corrode and rust, leading to unsightly appearance and potential structural weaknesses.

To prevent or minimize corrosion and rusting, it is important to properly maintain and protect your CFR exhaust system. Regular cleaning and inspection of the system can help identify any areas that may be prone to corrosion. Applying a high-quality protective coating or using stainless steel components can also help to prolong the lifespan of your exhaust system.

Carbon Build-up

Carbon build-up is another potential issue that owners may encounter with CFR exhaust systems. This occurs when unburned fuel and oil residues accumulate on the internal surfaces of the exhaust system, hindering the flow of exhaust gases and potentially reducing performance.

To address this issue, it is important to regularly clean your CFR exhaust system. This can be done by using a suitable cleaner or solvent to remove any carbon deposits. Additionally, regular maintenance of your vehicle’s air and fuel filters can help prevent excessive carbon build-up in the exhaust system.

Vibrations and Rattling Sounds

Some owners have reported experiencing vibrations and rattling sounds after installing a CFR exhaust system. These vibrations can be caused by various factors such as loose or improperly installed components, worn rubber hangers, or exhaust system resonance.

To address this issue, it is important to thoroughly inspect and tighten all components of the exhaust system. Additionally, replacing worn rubber hangers can help reduce vibrations. In some cases, installing an additional exhaust system damper or resonator can help reduce exhaust system resonance and minimize rattling sounds.

Excessive Heat Generation

Excessive heat generation is another potential problem that owners may encounter with CFR exhaust systems. While increased heat is a natural byproduct of improved exhaust flow, excessive heat can lead to potential damage to surrounding components and even pose a safety risk.

If you are experiencing excessive heat generation with your CFR exhaust system, it is important to check for any potential obstructions or restrictions in the system. Additionally, ensuring proper heat shielding and insulation around sensitive components can help mitigate heat-related issues.

Compatibility Issues with Other Components

When installing an aftermarket exhaust system, compatibility issues with other components can arise. This is particularly true for vehicles that have undergone extensive modifications or have non-standard configurations.

Before purchasing a CFR exhaust system, it is important to ensure that it is compatible with your specific vehicle and any other modifications that may be present. Consulting with a professional installer or contacting CFR directly can help determine the compatibility of the exhaust system with your vehicle.

Difficulties with Installation and Fitment

Lastly, some owners may encounter difficulties during the installation and fitment of CFR exhaust systems. These difficulties can include improper alignment of components, tight clearances, or the need for additional modifications to ensure a proper fit.

If you are experiencing difficulties during the installation and fitment process, it is recommended to consult a professional installer who has experience working with CFR exhaust systems. They can provide guidance and assistance to ensure a successful installation and proper fitment.


While CFR exhaust systems offer improved performance and sound for automotive enthusiasts, it is important to be aware of the potential issues that may arise. From excessive noise output to compatibility issues, addressing these problems promptly and correctly will help ensure a satisfactory experience with your CFR exhaust system. By understanding and addressing these common issues, you can enjoy the benefits of improved performance and sound without the frustration of unwanted problems.
