So, you have a need for speed and want to unleash your engine’s roar. One of the best ways to do that without compromising performance is installing an exhaust cutout. For the uninitiated, an exhaust cutout is a valve you install in your exhaust system that allows you to open or close the exhaust path at will. When the cutout is open, your exhaust flows straight through for a loud, rumbling sound that turns heads. When it’s closed, your exhaust flows through your muffler for a quiet, subdued tone. The best part is you can switch between the two with the flip of a switch from inside your vehicle. If you’re ready to experience the thrill of controlling the volume and tone of your engine’s voice, an exhaust cutout is a must-have modification. The rumble and roar will put a smile on your face every time you open it up. Here’s what you need to know to choose and install an exhaust cutout on your vehicle.
What Is an Exhaust Cutout?
An exhaust cutout is a valve installed in your vehicle’s exhaust system that allows you to open and close the exhaust pipe. When open, the cutout routes your exhaust gasses straight out, bypassing the muffler. This results in a louder, more aggressive sound from your engine and exhaust.
To install a cutout, you’ll need to cut your exhaust pipe and weld the cutout in place. The cutout includes flanges to connect the cut sections of pipe. Once installed, a cable runs into your vehicle’s cabin to a switch that controls the cutout valve. Flip the switch one way to open the cutout, and the other way to close it and send exhaust through your muffler as normal.
With the cutout open, you’ll experience the full, unmuted roar of your engine and gain a few extra horsepower as exhaust gasses flow more freely. Close the cutout for normal driving to avoid noise complaints! Installing an exhaust cutout is a great way for any gearhead to unleash the true sound of their vehicle’s powerplant.
Optional Control
For hands-free control, you can install an electronic cutout with a remote switch. This allows you to open and close the cutout on the fly without having to manually operate a switch in the cabin. An electronic cutout is more complex to install but provides an added level of convenience and cool factor.
Either a manual or electronic cutout can transform the sound of your ride and put a smile on your face every time you open it up! The deep growl of an unrestricted exhaust is music to any enthusiast’s ears. An exhaust cutout gives you the best of both worlds in one package.
Benefits of Installing an Exhaust Cutout
Installing an exhaust cutout on your vehicle has some sweet benefits.
For starters, it allows you to control the volume of your exhaust. You can go from a mellow rumble to an all-out roar with the flip of a switch or press of a button. ### The Best of Both Worlds
Want to keep the peace with your neighbors during the week? Close the cutout. Ready to announce your presence at the track on the weekend? Open ‘er up and let that V8 sing! An exhaust cutout gives you the best of both worlds.
Another perk is increased power. By opening the cutout, you decrease backpressure in the exhaust system, allowing your engine to breathe better and make more horsepower. On some vehicles, an exhaust cutout can improve performance by up to 10-15%.
Finally, an exhaust cutout just sounds awesome. The deep, throaty growl of an uncorked performance exhaust is music to any gearhead’s ears. Whether you have a custom exhaust system or a high-performance crate engine under the hood, an exhaust cutout lets that beast out of its cage.
For a few hundred bucks and a couple hours of work, an exhaust cutout can transform the sound and performance of your vehicle. Unleash the roar – your engine will thank you!
How to Choose the Right Exhaust Cutout for Your Vehicle
Choosing the right exhaust cutout for your vehicle depends on a few key factors. The most important considerations are:
Size
You’ll want an exhaust cutout that properly fits your vehicle’s exhaust pipe diameter. Measure your exhaust pipe to determine its size in inches—common sizes are 2.5 inches, 3 inches, and 3.5 inches. Choose a cutout within 0.5 inches of your measurement for the best fit. An exhaust cutout that’s too small won’t seal properly and will reduce performance, while one that’s too large is difficult to install and can also hamper performance.
Material
Stainless steel is the most durable and rust-resistant material for an exhaust cutout. It can handle high heat and last for years. Mild steel will rust over time, while aluminum may not withstand the high temperatures. Stainless steel cutouts typically cost a bit more, but are worth the investment for longevity and performance.
Installation style
Consider how you want to install the cutout—welded or clamp-on. Welded cutouts provide the most secure installation but require welding equipment and expertise to install. Clamp-on cutouts are easier to install yourself using the included clamps and gaskets, but may not seal quite as well as a welded unit. Choose based on your mechanical skills and how permanent of an installation you want.
Additional features
Some cutouts offer bonus features like a remote control to open and close the valve, a status indicator to show if it’s open or closed, and a muffler to reduce noise. Remote controls and indicators add convenience, while a muffler can make the cutout usable even when noise regulations are in effect. Consider if any of these added features are important for your needs.
