Is It Legal to Use an Exhaust Cutout?

Exhaust cutouts are devices that allow for modification of a vehicle’s exhaust flow. They are an easy way to make your car sound louder and enhance its performance, but the important question is whether or not they are legal. In this article, we will discuss what exhaust cutouts are and how they can be used, as well as whether or not they are legal and the potential implications of using them.

What Is an Exhaust Cutout?

An exhaust cutout is a device that can be fitted onto a vehicle’s exhaust system to enable it to bypass the muffler and provide increased airflow for improved power and sound. It works by allowing you to switch between two different exhaust systems: one with a muffler for normal driving, and one without the muffler for racing or enhanced performance. The cutout can easily be switched back to its original settings when desired.

How Are Exhaust Cutouts Used?

Exhaust cutouts have many uses in improving a vehicle’s performance, both in terms of power output and sound levels. A driver can use an exhaust cutout to bypass their mufflers during racing events or on days when they want to hear their engine roar. They can also be tuned to increase the power output of a vehicle by allowing more exhaust gases to pass through.

Potential Implications of Using an Exhaust Cutout

Using an exhaust cutout could potentially have some negative consequences, such as increased emissions and decreased fuel economy due to the increased airflow from the lack of a muffler system. However, these effects can be minimized with proper tuning and maintenance of the system. Additionally, it is important to note that using an aftermarket part or modifying any part of your vehicle’s emissions system can void its warranty and cause difficulty when trying to pass emissions tests or register for racing events.


In conclusion, it is important to remember that the legality of exhaust cutouts varies from state to state, and it is important to check your local laws before installing one on your vehicle. Additionally, using an exhaust cutout can potentially have some negative side effects, so it’s important to take these into consideration before making a decision.
