What’s Included?
The advertised kit contains:
- 2 electric exhaust valves
- 2 angled elbows
- 1 electronic control module
- 2 wireless remotes
- Wiring and installation accessories
That makes this the dual-valve configuration for vehicles where both sides of the exhaust need separate cutouts.
Built for Dual Exhaust Systems
The biggest difference between this kit and a single-valve cutout is simple:
there are two valves.
That makes it a better fit for many:
- Dual-exhaust V8 systems
- Muscle cars
- Performance trucks
- Restomods
- Street/strip cars
- Dual-pipe custom exhaust systems
A typical configuration may look like:
Left Header → 2.5″ Exhaust → Electric Cutout
Right Header → 2.5″ Exhaust → Electric Cutout
with both valves controlled together.
Three Exhaust Modes
This system provides three levels of exhaust control.
Fully Closed
With both valves closed, exhaust continues through the normal system.
Depending on the vehicle, that may include:
X-Pipe or H-Pipe → Resonators → Mufflers → Tailpipes
This is the quietest configuration.
Slightly Open
The intermediate mode opens the valves partially.
That allows some exhaust to exit through the cutouts while the rest continues through the conventional exhaust system.
This can create a louder, sportier sound without running the valves completely open.
Fully Open
Open both valves completely and the exhaust gains access to the shortest bypass route.
Depending on cutout location, the open path may bypass:
- Resonators
- Mufflers
- Long sections of tailpipe
This provides the most aggressive exhaust note.
Why Partial-Open Control Matters
Most traditional electric cutouts work like a light switch:
OPEN
or:
CLOSED
This kit adds a useful middle position.
That can be especially helpful on a street-driven performance car where fully open cutouts may be excessive for normal driving.
Instead of going directly from quiet to full mechanical violence, you get an intermediate setting.
Two Wireless Remotes
The system includes:
two wireless remotes
so one can be used as a backup.
The remotes communicate with the included control module, allowing both valves to be operated from inside or near the vehicle.
Benefits include:
- No permanent dashboard switch
- Convenient operation
- Backup remote included
- Control of all three valve positions
One Controller Operates Both Valves
The dual-valve kit uses:
one control module
for both electric valves.
That helps keep operation synchronized.
On a true dual exhaust, synchronized valve movement is preferable because both exhaust banks should generally switch modes together.
One side screaming through an open cutout while the other remains muffled is less “performance tuning” and more “electrical diagnosis pending.”
2.5-Inch Exhaust Compatibility
Each valve is designed for compatible:
2.5-inch exhaust tubing
which is approximately:
63.5mm
This size is common on many:
- Dual V8 exhaust systems
- Street-performance cars
- Performance trucks
- Restomods
- Moderate-output turbo builds
- Custom exhaust systems
Always measure the existing exhaust before ordering.
Dual 2.5-Inch Exhaust Has Significant Flow Area
Two 2.5-inch pipes provide far more total flow area than one 2.5-inch pipe.
That’s one reason dual 2.5-inch systems are common on:
- Small-block V8s
- LS-powered vehicles
- Classic muscle cars
- Performance pickups
Larger is not automatically better, but dual 2.5-inch exhaust can support substantial airflow when correctly designed.
Measure Before Ordering
Do not assume the exhaust is 2.5 inches based solely on an old receipt, forum post or previous owner’s memory.
Measure:
- Outside diameter
- Available straight tubing
- Valve clearance
- Elbow clearance
Also verify whether adapters will be required.
Our How to Install Exhaust Cutout the Right Way guide explains how to size and position electric exhaust cutouts correctly.
Two Angled Elbows Included
The kit includes:
two angled exhaust elbows
to help direct the open exhaust away from the underbody.
This is especially important on a dual system because there are two separate discharge points.
The outlets should not direct hot exhaust toward:
- Fuel tank
- Fuel lines
- Brake lines
- Wiring
- Transmission
- Driveshaft
- Rubber bushings
- Plastic panels
Proper orientation helps reduce heat exposure to nearby components.
Protect the Chassis From Exhaust Heat
An open exhaust cutout releases very hot exhaust gas underneath the vehicle.
The included elbows help redirect the exhaust, but they still need to be positioned correctly.
Check clearance from:
- Floorpan
- Fuel system
- Wiring
- Brake components
- Suspension
The goal is maximum exhaust sound without creating a new underbody heat-treatment program.
Weather-Resistant Electric Motors
The seller describes the valve motors as waterproof.
Unless a specific IP waterproof rating is documented, it is safer to describe them as:
weather-resistant electric motors
designed for underbody exposure.
The actuators may encounter:
- Road spray
- Dirt
- Dust
- Condensation
- Vibration
Avoid placing them where they will experience unnecessary standing water or direct high-pressure washing.
Keep the Motors Away From Extreme Heat
The valves operate directly in the exhaust stream.
The electric motors are more sensitive.
Whenever possible, keep the actuators away from extreme heat sources such as:
- Header collectors
- Turbochargers
- Catalytic converters
Moving the cutouts farther downstream can help reduce heat exposure.
Clamp-Friendly Installation
The seller advertises clamp-style installation for quick fitment.
Clamp connections can simplify installation when the tubing dimensions and geometry are compatible.
However, universal installation may still require:
- Cutting
- Welding
- Exhaust adapters
- Custom tubing
- Hangers
Treat this as a universal fabrication product rather than a vehicle-specific bolt-on kit.
Professional Installation May Still Be Best
For permanent street or performance builds, professional exhaust fabrication may produce a better result.
A good installation process is:
Measure → Cut → Fit → Tack → Check → Final Weld
Before finishing the installation, verify:
- Valve clearance
- Motor clearance
- Elbow direction
- Ground clearance
- Driveshaft clearance
- Suspension movement
- Wiring clearance
Check Installation Space Before Buying
The seller specifically advises checking available space underneath the vehicle.
That’s important because you need room for:
- Two valve bodies
- Two electric motors
- Two elbows
- Wiring
- Exhaust tubing
A true dual system can become crowded quickly.
Measure both sides independently rather than assuming the available space is symmetrical.
Can Dual Exhaust Cutouts Add Horsepower?
Potentially.
Opening both cutouts creates shorter exhaust paths and may reduce downstream restriction.
Whether that increases power depends on:
- Engine airflow
- Headers
- Catalytic converters
- Exhaust diameter
- Muffler restriction
- Engine tuning
A modified V8 running through restrictive mufflers may respond differently from a stock engine with an efficient exhaust.
Do not advertise a guaranteed horsepower gain.
V8 and Muscle-Car Applications
This dual-valve configuration is particularly well suited to V8 vehicles with true dual exhaust.
Potential applications include:
- Mustangs
- Camaros
- Corvettes
- Challengers
- Chargers
- Classic muscle cars
- LS swaps
- Performance trucks
- Restomods
With both valves fully open, the exhaust character can change dramatically.
Especially on a cammed engine.
Subtlety left the conversation several modifications ago.
X-Pipe and H-Pipe Systems
Dual electric cutouts can be incorporated into exhaust systems using:
- X-pipes
- H-pipes
Valve placement may be before or after the crossover depending on:
- Available space
- Desired sound
- Exhaust design
Our X Pipe vs H Pipe: Which Sounds Better? guide explains the differences between these layouts.
Turbocharged Applications
Dual 2.5-inch exhaust can also appear on some turbocharged or twin-turbo builds.
Potential benefits from opening the cutouts depend on:
- Turbocharger size
- Downpipe layout
- Exhaust configuration
- Catalytic converters
- Mufflers
- Boost pressure
- Calibration
The cutouts should complement a properly sized exhaust rather than compensate for an undersized system.
Works With Custom Cat-Back Systems
The valves can also be integrated into a custom cat-back exhaust.
With the valves closed:
normal muffled cat-back
With the valves partially open:
sportier intermediate sound
With the valves fully open:
maximum bypass
For more information on exhaust layouts, read our Catback Exhaust vs Axleback: Which Wins?.
Wiring the Dual-Valve System
Because two motors are controlled by one module, wiring should be routed carefully to both sides of the vehicle.
Keep the harness away from:
- Exhaust tubing
- Catalytic converters
- Driveshaft
- Suspension
- Sharp sheet metal
Use appropriate:
- Circuit protection
- Connections
- Wire loom
- Heat protection
- Harness retention
Loose wiring under a vehicle tends to discover rotating components with impressive efficiency.
Test Both Valves Before Final Installation
Before permanently welding or clamping the system into place, connect the electronics and test both valves.
Verify:
- Both fully close
- Both reach partial-open
- Both fully open
- Both operate at similar speed
- Both remotes work
- No valve binds
If one valve behaves differently from the other, diagnose it before completing the exhaust fabrication.
Check for Exhaust Leaks
After installation, test the system with both valves fully closed.
Inspect:
- Valve flanges
- Clamps
- Welds
- Existing exhaust joints
Watch for:
- Soot
- Ticking
- Exhaust smell
Then operate the valves in partial and full-open modes.
Recheck all hardware after the first several heat cycles.
Two-Year Advertised Warranty
The seller advertises a:
2-year warranty
and states qualifying component failures may be replaced during that period.
Always verify current warranty terms before purchase.
Check whether coverage includes:
- Motors
- Valves
- Control module
- Remotes
- Wiring
- Labor
- Shipping
A parts warranty does not necessarily reimburse the labor required to remove a welded exhaust valve.
Street-Legal Considerations
Electric cutouts can be restricted on public roads.
Potential issues include:
- Exhaust-noise laws
- Muffler requirements
- Exhaust bypass restrictions
- Emissions regulations
For California readers, our Is My Exhaust Legal? guide provides additional background.
Always confirm current state and local requirements.
Don’t Bypass Required Emissions Equipment
Do not install or operate the valves in a way that unlawfully bypasses required:
- Catalytic converters
- Oxygen sensors
- Other emissions-control equipment
A street-oriented system should preserve required emissions components.
Single vs. Dual Electric Exhaust Cutouts
Choose the configuration based on the exhaust.
Single Valve
Best suited to:
- Single exhaust pipe
- Merged exhaust systems
- Single-pipe turbo builds
Dual Valve
Best suited to:
- True dual exhaust
- Dual-bank V8 systems
- Two independent exhaust pipes
This kit is the:
dual-valve configuration.
If your vehicle only has one pipe at the intended installation point, buying two valves mostly gives you a spare with commitment issues.
