What is an Exhaust Cutout?

An exhaust cutout is an opening in the exhaust system that enables drivers to bypass the muffler and divert an increased amount of exhaust through the pipes, producing a significantly louder and more aggressive sound. It is typically placed between the exhaust manifold/header and the mufflers within the exhaust system. Normally, the cutout opening is capped, and the exhaust gases are forced through the muffler, which produces the standard sound. However, when the valve is opened, the exhaust gases bypass the muffler and flow out directly from the exhaust, resulting in a much louder sound. This also has the potential to improve the vehicle's performance by decreasing backpressure and increasing horsepower.

How Do Exhaust Cutouts Work?

Exhaust cutouts are a popular modification for car enthusiasts looking to increase their engine's power output and sound. The installation process involves placing the cutout between the header and the muffler in the vehicle's exhaust system. The cutout has two regions, one that leads towards the muffler and the other dependent on the modification. The driver can control the exhaust flow by using an electrical link to the dashboard, allowing them to open and close the cutout with the press of a button. When the cutout is open, the exhaust fumes bypass the muffler, creating a louder engine sound. By closing the cutout, the exhaust returns to its original flow, resulting in a more subtle sound. Exhaust cutouts give drivers the ability to control the sound of their vehicle with ease.

Benefits of Buying Exhaust Cutouts

One major benefit of buying exhaust cutouts is that they can help to increase horsepower and torque. By reducing backpressure in the exhaust system, more air can flow into the engine, leading to improved combustion and increased power output. Additionally, because there is less restriction in the system, acceleration times can also be improved.

Another advantage of installing an exhaust cutout is that it provides greater control over your vehicle's sound profile. Some drivers prefer a more aggressive and loud exhaust sound, while others may desire a quieter, more refined engine note. With an exhaust cutout, you can easily switch between these two modes with the push of a button.

Fast shipping and super smooth installation. Freed up so much restriction on my 2015 Chevy 3500HD. Sounds healthy, truck breathes much better, and mpg improved noticeably on the highway. Solid product from SuncentAuto!

Wanted to share a quick video of the pipes before I get them on. This is the T-409 stainless version, and as you can see, it looks great. Much better than the old aluminized pipes I had. It's a simple, straight-through design that should remove all the restriction. I can't wait to install it. If you're looking for a simple, budget-friendly option, watch the video to see the quality.

Got this 4-inch downpipe-back kit for my 12 GMC Sierra. The performance gain is night and day! Spool-up time is way faster, and my EGTs dropped significantly when hauling my heavy trailer. The T-409 stainless construction feels heavy-duty. Paired it with a proper tune and the truck runs smoother than ever. Highly recommend for any LML owner!

The PCV reroute keeps the intake dry. Big win for my 2023 truck.

Couldn’t be happier with this downpipe. My cat got stolen more than once and I was done paying big bucks for another converter. This setup saved me cash and gave the car a way cooler sound.

This is hands down one of the best upgrades I've done for my '06 6.0L Powerstroke. With the exhaust restriction gone, the turbo spools up way faster, and the throttle response is significantly sharper. The best part is seeing a noticeable drop in my EGTs, which gives me peace of mind for engine longevity. I even noticed a slight bump in fuel economy on highway trips, maybe 3-4 MPG better.

I'm genuinely impressed with the Suncent Exhaust Header for my E46. The packaging was exceptional—everything arrived securely sealed with zero shipping damage. Fitment was nearly spot-on, though I encountered a couple of minor hurdles. I needed to slightly adjust the engine mount bracket for a perfect fit, which was a quick and easy tweak. Additionally, the O2 bung placement required a minor firewall modification, but this is a common step with most aftermarket headers for the E46 and was straightforward to resolve. One suggestion: I recommend using OEM header gaskets over the ones included in the kit. The OEM gaskets provide a superior seal, better fit, and improved heat protection for the upper plastic valve cover. Overall, I'm thrilled with the headers. They’re a fantastic upgrade for the E46, and despite the small adjustments, the installation was smooth and hassle-free. Great job, Suncent!
