1. DMH Performance Low Profile Electronic Exhaust Cutout: Best Overall
In our evaluation, the DMH Performance Low Profile cut out stands out for its robust build and excellent fitment. The stainless steel body and sealed motor are designed to withstand harsh exhaust environments, and owner feedback consistently praises its longevity. We found the low profile design particularly beneficial for trucks with limited clearance, as it avoids scraping on uneven terrain.
However, the motor emits a noticeable whirring sound during operation, which some users find distracting. If absolute silence during actuation is a priority, you might prefer a unit with a quieter gear train. Also, the wiring harness could be longer for easier routing on larger trucks. Despite this, for most truck owners seeking a durable and effective cut out, this is a top choice.
- Low profile design fits tight underbody spaces without sacrificing ground clearance.
- Heavy-duty stainless steel construction resists corrosion and heat damage.
- Smooth operation with a sealed motor that prevents moisture intrusion.
Pros: Very compact and easy to mount on most trucks.; Reliable motor with positive user reviews over years of use.
Cons: Motor can be noisy when operating compared to some competitors.
2. QTP Electric Exhaust Cutout Kit: Best for Sound Control
QTP’s kit is a popular choice for those who prioritize convenience. The included remote control works reliably, and the motor operates quietly. Based on owner feedback, the aluminum body holds up well under normal driving conditions, but we noted concerns about long-term durability in high-heat applications like turbocharged trucks. The butterfly valve seals tightly when closed, preventing exhaust leaks.
That said, the aluminum construction is a trade-off. If you frequently drive in extreme conditions or run a high-horsepower setup, the DMH stainless steel option may last longer. Also, some users reported the remote control signal can be weak through thick vehicle panels. For daily driven trucks where weight savings matter, this is a solid pick.
- Remote control operation allows easy opening and closing from inside the cab.
- Aluminum body reduces weight but still offers good corrosion resistance.
- Butterfly valve design provides a clean seal when closed.
Pros: Convenient remote control with good range.; Smooth, quiet motor operation.
Cons: Aluminum may dent or warp under extreme heat compared to stainless steel.
3. Pypes Performance Exhaust Cutout: Best Value
For budget-conscious truck owners, the Pypes manual cutout offers great value. The 304 stainless steel body matches the durability of much pricier units, and the cable actuation is simple and foolproof. We found the installation straightforward, though routing the cable into the cab requires some DIY effort. Owner reviews highlight that it seals well when closed and produces a noticeable sound increase when open.
However, the manual operation means you cannot adjust it on the fly without pulling a knob or lever. If you want remote control or automatic opening, this is not for you. Also, the cable can bind if not properly lubricated. For those who prefer a mechanical solution that will not fail electronically, this is an excellent choice.
- Affordable manual cutout with a simple cable actuation system.
- 304 stainless steel construction provides excellent corrosion resistance.
- Compact design fits most truck exhaust systems.
Pros: Very affordable for a stainless steel cutout.; Manual operation is reliable and never fails electronically.
Cons: Requires running a cable into the cabin, which can be tricky to route.
4. MagnaFlow Exhaust Cutout: Premium Build
MagnaFlow’s cutout lives up to the brand’s reputation for quality. The T-304 stainless steel is top-tier, and the valve seals perfectly. In our comparison, this unit had the tightest tolerances, which translates to no exhaust leaks when closed. Owner feedback confirms long-term reliability, with many reporting years of trouble-free use.
That said, the premium price may be hard to justify if you only want occasional noise. Also, the motor is slightly bulkier than some low-profile designs, which could be an issue on trucks with very limited space. If you prioritize longevity and a perfect seal and are willing to pay more, this is a great choice.
- High-quality T-304 stainless steel for maximum corrosion resistance.
- Precision-machined butterfly valve for a leak-free seal.
- Includes a weatherproof motor and wiring harness.
Pros: Exceptional build quality from a trusted brand.; Leak-free operation even after extended use.
Cons: Higher price point than many competitors.
5. Flowtech Exhaust Cutout: Budget Pick
Flowtech’s cutout is the most affordable we evaluated. It uses a mild steel body with a ceramic coating to slow rust. For occasional use in dry climates, it can be a functional solution. The manual cable system works reliably, and installation is simple. However, based on owner feedback, the coating can chip, leading to rust within a year or two in wet conditions.
If you live in an area with road salt or high humidity, skip this pick. The durability is simply not there. Also, the valve may not seal as tightly as stainless steel options, causing minor exhaust leaks. For a weekend toy that sees limited use, it may suffice, but we recommend spending more for longevity.
- Lowest cost option for those on a tight budget.
- Ceramic coating offers some corrosion protection.
- Manual cable operation with simple installation.
Pros: Very inexpensive entry point.; Cable actuation is straightforward.
Cons: Mild steel will rust over time, especially in salt-belt states.
6. BBK Performance Electronic Exhaust Cutout: Compact Design
BBK’s cutout is designed for maximum clearance. Its low profile makes it a favorite for trucks with aftermarket suspensions or limited space. The stainless steel body and sealed motor are well-made, and owner reviews note consistent performance. We found the installation easy, especially in tight areas where larger units would not fit.
However, the 2.5-inch diameter restricts exhaust flow compared to 3-inch options. If your truck makes over 400 horsepower, this could become a bottleneck. Also, the motor is a bit slower to open than some competitors. For stock to mildly modified trucks that need space savings, this is a good fit.
- Ultra-low profile design fits in tight exhaust tunnels.
- Stainless steel construction for durability.
- Motor is sealed against moisture and road debris.
Pros: Very compact; ideal for lowered trucks or tight spaces.; Good build quality with a reliable motor.
Cons: Only available in 2.5-inch size, limiting flow for high-HP builds.
7. Hooker BlackHeart Electronic Exhaust Cutout: Performance Oriented
Hooker’s BlackHeart cutout targets enthusiasts seeking maximum performance. The high-torque motor is a standout feature, as it can open even when the exhaust is under pressure. The 304 stainless steel construction is solid, and owner feedback notes a clear power increase when open on naturally aspirated and forced induction trucks. We compared dyno results from users and saw consistent gains of 5-10 horsepower.
However, we found that the motor reliability is not as robust as the DMH or MagnaFlow units. Some owners reported the motor failing after 2-3 years, requiring replacement. The price is also on the higher side. If you are building a track-focused truck and want every bit of performance, this is worth considering, but for daily driving, a more reliable option may be better.
- High-torque motor ensures reliable opening even with exhaust backpressure.
- 304 stainless steel body and butterfly valve for corrosion resistance.
- Designed for high-performance applications with a focus on flow.
Pros: Motor has plenty of torque to open under load.; Good flow when open, noticeable performance gain on dyno sheets.
Cons: Higher price point and some reports of motor failure after a few years.
Frequently Asked Questions
Are exhaust cut outs legal on the street?
Exhaust cut outs are generally intended for off-road or track use only. Many states and municipalities have noise ordinances that prohibit modifying the exhaust to bypass the muffler on public roads. Check your local laws before installing a cut out, as you may face fines or emissions test failures.
Will an exhaust cut out cause a check engine light?
An exhaust cut out itself does not directly trigger a check engine light since it is downstream of the oxygen sensors. However, if the cut out is placed before the O2 sensors, it can cause incorrect readings and trigger a code. Most installations are after the sensors, so it is typically safe.
How do I choose between manual and electric cut outs?
Manual cut outs are cheaper and more reliable but require a cable into the cabin and cannot be adjusted on the fly. Electric cut outs offer remote control and convenience but have more parts that can fail. For daily driving, electric is more practical; for a budget or track-only build, manual works fine.
Can I install an exhaust cut out myself?
Yes, many DIYers can install a cut out with basic tools like a saw, clamps, and a drill. However, welding is recommended for a leak-free seal. Electric models require wiring to a power source and a switch. If you are not comfortable with exhaust work, a professional installation is advisable.
Will a cut out reduce backpressure and hurt low-end torque?
Opening a cut out reduces backpressure, which can decrease low-end torque on some engines. However, on modern trucks with variable valve timing, the effect is often minimal. For maximum performance, many users report gains in the mid-to-high RPM range. Test and tune to see if it suits your driving.
