If you’re an automotive enthusiast looking to amplify your car’s sound and performance, an exhaust cutout might be the perfect upgrade. This modification gives drivers the ability to control exhaust flow, allowing for an aggressive, racecar-like roar at the push of a button while keeping things street-legal when needed.
In this comprehensive guide, we’ll explore everything you need to know about car exhaust cutouts, including how they work, their benefits, installation, and whether they’re legal in your area. Plus, we’ll introduce you to Spelab Auto Parts, a top provider of high-quality exhaust cutouts and performance parts.
What is an Exhaust Cutout?
An exhaust cutout is a device installed in a vehicle’s exhaust system that allows drivers to bypass the muffler and catalytic converter, directing exhaust gases straight out of the pipe. This results in an unrestricted, louder, and more aggressive exhaust note, while also potentially increasing horsepower and torque by reducing backpressure.
Exhaust cutouts come in two main types:
- Manual Cutouts – Require physical adjustment, usually by unbolting a cover to open or close the cutout. These are simple but lack convenience.
- Electronic Cutouts – Controlled via a remote or switch inside the car, allowing instant toggling between a muffled and open exhaust system. These are the most popular due to their ease of use.
Benefits of Installing an Exhaust Cutout
1. Increased Performance
By reducing exhaust backpressure, cutouts can improve engine efficiency and allow for a small horsepower boost, especially in high-performance vehicles.
2. Aggressive Sound on Demand
A cutout lets you switch from a quiet, street-friendly exhaust tone to a loud, race-ready roar at the push of a button.
3. Customizable Exhaust Flow
With an electronic cutout, you can fine-tune how much of your exhaust gases bypass the muffler, giving you control over sound and performance.
4. Track-Ready Performance
For track or drag racing, an open exhaust allows for better throttle response and power output, helping you achieve better lap times.
5. Cost-Effective Upgrade
Compared to a full exhaust system replacement, a cutout is an affordable way to achieve a more aggressive sound and improved performance.
How to Install an Exhaust Cutout
Installing an exhaust cutout is a moderate-level DIY project, but it’s recommended to have a professional handle it if you’re unfamiliar with exhaust work.
Tools & Materials Needed:
- Exhaust cutout kit (available at SpelabAutoParts.com)
- Cutting tool (angle grinder or reciprocating saw)
- Welding equipment or clamps
- Wrenches and socket set
- Drill (for electronic cutout wiring)
Step-by-Step Installation:
- Choose the Installation Spot: Locate a section of your exhaust pipe before the muffler where the cutout will be installed.
- Cut the Exhaust Pipe: Using an angle grinder or reciprocating saw, carefully cut a section of the exhaust pipe to fit the cutout.
- Attach the Cutout: Depending on the kit, you may weld the cutout in place or use clamps for a bolt-on installation.
- Connect the Wiring (for Electronic Cutouts): Route the wiring from the cutout motor to a switch inside your car’s cabin.
- Test the System: Start the engine and toggle the cutout switch to ensure proper function and no leaks.
For a hassle-free installation, consider Spelab Auto Parts’ exhaust cutout kits, which come with all necessary components and easy-to-follow instructions.
Are Exhaust Cutouts Legal?
The legality of exhaust cutouts varies by location. In many areas, open exhaust systems are illegal for street use due to noise regulations. However, when used responsibly and closed during regular driving, cutouts may be permissible.
How to Stay Legal:
- Check local noise laws before installing an exhaust cutout.
- Use cutouts only on private property or race tracks.
- Keep the cutout closed while driving in residential areas.
For compliance-friendly options, Spelab Auto Parts offers high-quality cutouts designed for both street and track use.
