5 Best Electric Exhaust Cutout Reviews

After scouring the market for hours, we finally decided to keep only 7 cutouts in our exclusive list for today. So, here are the 7 best electric exhaust reviews you have been waiting for all this while. Trust us when we say that you will come to love every single one of these.

1. QTEC30 Electric Exhaust Cutout

Recently, the QTEC30 from QuickTime Performance has been everyone’s number-one choice for electric exhaust cutouts. It’s reliable, affordable, and user-friendly – everything you could hope to get from a cutout of such stature.

Key Feature

• Aluminum build
• Single toggle switch
• Well-founded wire harness
• 3.00″ Electric Valve
• Easy installation

Specifications

Quality Material

Unlike other cheap cutouts, the QTEC30 isn’t made from low-quality steel or alloy. Rather, it’s manufactured from high-grade aluminum that ensures both quality and sustainability.

In addition to a premium build, the aluminum provides great resistance against corrosion damage. That said, the cutout itself isn’t waterproof. But the aluminum framework is enough to make sure that it doesn’t cause any permanent damage in the long run.

Sturdy Build

Alongside aluminum, the manufacturers included stainless-steel chassis in the framework of this electric exhaust cutout. And that amplifies the overall rust-resistance abilities and provides integrity at the same time.

Furthermore, the optional Y-pipe strategy is a top-of-the-line feature that helps with the proper placement of this cutout. When applied correctly, the exhaust cutout will maintain its position even when all hell breaks loose.

Perfect Fitting

Almost all customers face this problem while purchasing a new cutout for their car, especially if it’s an old model. The valve positioning is either too wide or too narrow for the electric exhaust cutout to squeeze in between.

But QuickTime Performance utilizes laser rays to manufacture the QTEC30 exhaust cutouts. As a result, these cutouts provide, quite literally, a laser precision fitting in all scenarios.

High-End Functionality

Another troublesome fact about normal electric exhaust cutouts? You’ll need to get under the car to install these little guys, so your car doesn’t make as much sound. Not only that, you’ll have to go under over and over again if you need to adjust the exhaust levels. 

Needless to say, not everyone knows how to do that. And thus, they have no choice but to go to the professionals. But with the QTEC30 electric exhaust cutout, you wouldn’t have to ask for someone else’s help any longer.

Well, maybe just once to get the cutout up and running, i.e., installed for the first time. After that, you can simply control it with a two-way switch to manipulate the exhaust level however you want. 

Pros:

• Excellent aircraft body made of aluminum
• Cuts are not often overheated
• Installing & replacement in a matter of seconds
• Aftermarket parts are widely available

Cons

• Leakage may occur due to incorrect installation
• Doesn’t come with gaskets or bolts

Editors Opinion:

Exhaust cutouts from Quick Time Performance are well-known for their size variations, which allow them to fit almost any vehicle’s exhaust system.

Also, this product also includes y-pipe cuts, allowing you to maximize your vehicle’s performance. As a result, you will attract the attention of everyone you meet.

2. SPELAB Electric Exhaust Cutout

In addition to the detailed explanation, you’ll receive a full-on cutout valve kit within the package. This kit will make all your work a lot easier. It includes a control box alongside the usual motor and the extension harness. 

And it doesn’t just stop there. You’ll also receive a wireless remote control system within the package. It doesn’t require any battery, and thus, you can systematically use it to control the apparatus right from your seat.

High-End Installation

Since the mechanism is a little complex, it’s best to call in professionals for the installation. Only attempt to try it out personally if you’re fully convinced of your mechanical skills.

Other than that, there are no issues with the installation procedure itself. It’ll fit in with any vehicle as long as the exhaust size stretches out to 3.0 Inches. And if you have the Butt Joint Exhaust Band-Clamp from SPELAB, it’ll make the installation all the easier.

Perfect For Single Exhaust Pipes

Nothing else can top this one in a particular league in the list for the top-rated electric exhaust cutout. And that’s compatibility with single exhaust pipes for all sorts of vehicles without any discrimination.

This cutout was pretty much designed to take care of all the annoying noises coming out of single exhaust pipes. And if you happen to own one such vehicle, you know exactly what we’re talking about. Sleeping next to a snoring person is nothing compared to tolerating the noises coming out of these pipes.

Fortunately, this cutout is built to get rid of such noises or at least minimize them to a certain extent. Additionally, it ensures smooth gas flow and helps you to gain better control. It’s practically a performance booster, considering how it promotes conduction.

• The deep and resonant sound
• It may be used with most automobiles
• Extremely long-lasting functionality

Cons

• Doesn’t come with clamps
• The valve motor’s not waterproof

Editors Opinion:

3. Granatelli Motorsports 307530C 

Next up on the list for the best electric exhaust cutout, we have the Motorsports 307530C  from Granatelli. It’s a simple and to-the-point cutout kit, and that’s what makes it special. You won’t have to waste your time dealing with extravagant features just to make it work.

Specifications

Bolt-in Style

Surprisingly enough, even the best electric cutouts can often just fall apart in extreme conditions. Most often than not, it’s when the vehicle jerks a lot while riding up and down around the rough terrains.

And that’s also why many professionals tend to advise against using exhaust cutouts during trips like these. However, with the Granatelli Motorsports 307530C  by your side, you won’t have to worry about this as much.

Because the bolt-in style of the cutout will make sure the device stays in its place at all times. And just because it doubles down on the grip security doesn’t mean that it’ll impact the mobility by any means. Zero motor noise and a smooth ride – you’ll get to enjoy it all!

Hybrid Framework

This cutout makes the best use of both worlds. Instead of sticking to a certain build, it utilizes the durable infrastructure of aluminum as its main bodywork. And not only that. It’s made with CNC 6061 Aluminum, which is practically an aerospace-grade aluminum alloy.

In other words, this alloy has excellent corrosion resistance abilities and a great strength-to-weight ratio. Perfect for keeping the cutout outlet secure for years to come.

As for the bearings like shafts and blades, it mostly uses stainless steel. Hence, they’re protected against both water and rust damage.

360-Degree Rotation

The Granatelli Motorsports 307530C comes with a V-Band Style Clamp within the cutout. The specialty of this clamp is that it can allow up to 360-Degree rotations for the turn-downs. Hence, fixing the exhaust levels doesn’t seem so excruciating and time-consuming anymore.

Energized Performance

The Motorsports 307530C improves vehicle performance in at least three different ways. Firstly, the aluminum build is extremely temperature-resistance. So, it keeps the motor safe from overheating and thus, keeps it from disrupting the usual performance level.

Secondly, the cutout comes with high-torque motors. These DC gears will not only smoothen the overall performance but will also improve the rate of transmission. Additionally, it’s a smart chip motor, i.e., you can easily control it with the One-Touch rocker switch everywhere. 

Pros

• Bolt-in style cutout for extra security
• High-grade materials for the price
• Stainless steel blades and shafts for smooth gliding
• 360-Degree V-Band rotation for enhanced performance
• Highly durable due to sealed internal and external components

Cons

• Slight leakage issues when installed incorrectly

Editors Opinion:

It is possible to have a compact and leak-free design with the 307530C electronic exhaust cutoff kit. It is also wirelessly operated and necessitates a two-wire connection to the battery to get started.

How To Choose The Best Electric Exhaust Cutouts?

While shopping for new electric cutouts, here’s what you need to keep in mind.

Material

The material directly affects the durability of the cutout. If it’s manufactured from cheap steel or alloy, the cutout will come apart in a matter of days.

Hence, the quality of the materials matters a lot. One of the best materials for e-cutouts nowadays is aircraft-grade aluminum alloy. Stainless steel (preferably T-304) works like a charm too, in terms of lightweight construction and rust resistance.

Valve Size

Depending on the narrowness of your valves, you’ll need to get a cutout accordingly. For instance – a 3.00″ pipe cutout won’t be able to accommodate a narrow valve of 2.25″. So, measure correctly before looking for valves.

Installation Requirements

Some cutouts require professional installation since they have an advanced design. So, if you don’t want to rely on the mechanics, get the cutouts with a comparatively simplistic design.

Ease-Of-Use

Some cutouts will require hands-on fixing while it’s possible to control the others separately. Hence, read up on the maintenance guide thoroughly unless you want to go under the car every other day.

6 Easy Steps For Installing An Electric Exhaust Cutout: 

Here are some amazing steps to install an electric exhaust cutout safely. Read & apply it for the safest installation.

Step 1: Be sure that the electric cutout is centered in the exhaust cutout flange aperture before attaching it with bolts to the exhaust cutout. The side of the device has a tiny cleaning/lubrication port. Ports on each side of a butterfly valve must be cut out for the cutout to function correctly.

Step 2: Long periods of inactivity may cause the butterfly assembly to accumulate carbon exhaust deposits, causing it to get stuck in the closed position.

Step 3: You don’t have to dismantle the exhaust system to clean or lubricate the cutout with this port. A carburetor-type cleaning and penetration spray lubricant should be utilized.

Step 4: The switch should be installed at the desired place. As a reference point, the white wires from a harness pigtail would indicate the switch’s open state, as seen in the diagram below.

Step 5: Use a chassis ground or the negative battery post to connect the switch’s black wire. It is recommended that you connect the green wire to a 12-volt key-on ignition source. With this exhaust cutoff, a 5 Amp fuse is all you need.

Step 6: Be cautious to avoid heat sources or moving items when routing the harness to the electric cutouts.

Attention! When the exhaust system is excellent, you should clean the exhaust cutout. A heated exhaust system should not be washed or lubricated! A fire may occur as a consequence of this action!

Safety Warnings For Using An Electric Exhaust Cutout

• When the cutout butterfly reaches its fully open or closed position, instantly press the switch to shut or open it. You risk blowing a fuse or over-stressing the cutoff motor if you don’t.
• When activation, keep a safe distance from the exhaust cutouts.
• If this isn’t done, there’s a chance someone may be hurt. Cutout’s motor is powerful enough to harm palms or fingers.
• This practice is prohibited by law in most states.
• Don’t take your car off the beaten path if you’re concerned about the exhaust components coming into close touch with grass, shrubs, or other flammable things. This might result in a fire.
• Modifications to a vehicle’s exhaust system may impact a variety of electrical sensors and systems.

Frequently Asked Questions

Do Exhaust Cutouts Increase Horsepower?

Exhaust cutouts may make the vehicle sound louder, but you won’t get the precise sound you’re looking for. It’s possible to improve your car’s horsepower and torque by installing an aftermarket exhaust and then adding exhaust cutouts, but most factory and stock exhausts don’t let you do that.

Do Exhaust Cutouts Work?

It’s possible to damage eardrums at will and then calmly walk away from the crime scene thanks to exhaust cutouts Not a new thing, these exhaust cutouts. They’ve probably been around longer than mufflers themselves when it comes to dampers themselves.

Do You Need A Tune For Exhaust Cutouts?

Compared to a regular exhaust, a cutout decreases back pressure, but probably not as much as replacing downpipes. A single piece of music cannot meet both prerequisites.

How Long Do Exhaust Cutouts Last?

Before the muffler, you need one cutout added if you are presently using a factory exhaust system. The quality of a product determines its lifespan, so do your research and choose wisely. Others will have to share their own stories, but I’ve seen them last between six months and two years.

How Long Does It Take To Install Exhaust Cutouts?

It should take no more than two hours to complete the installation. The construction of the building is divided into two stages. You don’t have to perform them in that sequence.

Can electric exhaust cutouts stop the noise coming out of a vehicle?

Not completely. But they can help to minimize it.

Do E-cutouts make a car faster?

Depends on the performance level. If cutouts can ensure smooth gas flow, they can indirectly improve the performance level of the car.

Why do cutouts leak air?

Normally, they shouldn’t. If they’re leaking, it’s most likely an installation or tightening issue.

Final Verdict

Hopefully, by now, you’ve found the perfect cutout for your exhaust system.

But if you need a little bit of a recap, here’s it. We’d recommend going for the QTEC30 E-Cutout since it’s our top choice in all aspects. Manufactured from high-grade materials, these cutouts ensure low noise during operation. A win-win situation from both ends, if you ask us.

However, the SPELAB one isn’t bad either if you prefer low-key exhaustion. And finally, you can always go for the Motorsports 302530 if you’re looking to settle down for improved performance.
