NS 400Z Exhaust

Valvetronic Exhaust Module Switch Control Automatic (Electric) The Valvetronic Exhaust Module Switch Control Automatic (Electric) is an electronic control unit intended to operate exhaust systems that use an internal exhaust valve to regulate exhaust gas flow. Valved exhaust systems are designed to alter exhaust behaviour by opening or closing a valve within the exhaust path, allowing the system to shift between different sound and flow characteristics. In a typical valved exhaust setup, the exhaust valve controls how exhaust gases exit the system. When the valve remains closed, exhaust gases are routed through a more restrictive internal path, resulting in a quieter exhaust note and controlled gas flow. When the valve opens, exhaust gases are allowed to pass through a freer-flowing route, which increases exhaust sound output and reduces flow restriction. This module enables that valve movement to be controlled electronically using an electric actuator. Electronic Valve Control Concept This exhaust module replaces traditional manual cable mechanisms or vacuum-based exhaust valve systems with an electrically actuated control method. Instead of relying on mechanical cables or engine vacuum, the system uses electrical signals to control the opening and closing of the exhaust valve. By using electric actuation, the system allows more direct and consistent valve operation. The exhaust valve responds to electrical input rather than physical cable tension or vacuum pressure, reducing dependence on mechanical components that may stretch, degrade, or lose effectiveness over time. The control unit sends signals to the electric exhaust valve actuator, which physically moves the exhaust valve between open and closed positions. This process allows the user to manage exhaust behaviour through electronic switching rather than manual intervention. Exhaust Mode Switching The module is designed to allow switching between different exhaust valve positions. This switching enables the user to alternate between a quieter exhaust mode and a freer-flowing exhaust mode depending on preference or operating conditions. Some systems of this type may support an automatic control mode, where the valve position changes based on preset conditions such as engine speed or throttle input. Manual control is also possible through a wired push-button or switch interface. The exact operating behaviour depends on the configuration of the connected exhaust system and actuator. The module itself does not generate exhaust sound, alter exhaust piping, or modify internal exhaust construction. Its function is limited strictly to controlling the valve position within a compatible valved exhaust system. Installation & System Integration The Valvetronic Exhaust Module Switch Control Automatic (Electric) is presented as a plug-and-play style electronic module intended to integrate with compatible valved exhaust systems. Installation involves connecting the control unit to the electric exhaust valve actuator using the supplied wiring harness and connecting the module to an appropriate power source from the vehicle’s electrical system. Typical installation steps include: Mounting the control module securely on the vehicle Connecting the wiring harness to the exhaust valve actuator Installing the push-button or control switch in an accessible location Ensuring proper power supply and electrical grounding The product description does not indicate any requirement for permanent engine modification. However, because exhaust valve designs, wiring layouts, and electrical systems vary between vehicles and exhaust manufacturers, compatibility must be verified prior to installation. Professional installation is recommended for users who are not familiar with vehicle electrical systems or exhaust components. Intended Application This module is intended for use with exhaust systems that: Incorporate a valved exhaust mechanism Use or support electronic exhaust valve actuation The product is categorized as a universal aftermarket exhaust control module. It is not vehicle-specific by default. Fitment depends entirely on the exhaust valve type, actuator compatibility, electrical requirements, and available mounting space on the vehicle. The module does not replace an exhaust system, muffler, or exhaust valve. It functions solely as a control interface for an existing compatible valved exhaust setup. What’s Included Based on the product presentation and information provided, the package includes: Valvetronic Exhaust Module Switch Control unit Electric actuator interface and wiring harness Push-button control or switching interface Only components shown or explicitly implied are included. No additional adapters, exhaust valves, mounting brackets, or vehicle-specific hardware should be assumed unless specified by the seller. Compatibility & Important Notes This product functions only with compatible valved exhaust systems that support electronic valve control. Vehicle-specific compatibility is not guaranteed. Buyers must confirm: Exhaust valve type and actuation method Electrical compatibility with the control module Physical mounting feasibility Local noise regulations and road-use laws may apply depending on exhaust configuration and valve operation. Compliance with applicable regulations is the responsibility of the vehicle owner. Summary The Valvetronic Exhaust Module Switch Control Automatic (Electric) is an electronic exhaust valve control unit designed to operate compatible valved exhaust systems using electric actuation. It provides an alternative to mechanical or vacuum-based valve control by offering electronically managed exhaust valve operation. As a universal aftermarket module, careful compatibility verification is required before purchase and installation. The module does not modify exhaust hardware or create exhaust sound; it only controls valve position within a compatible exhaust system.

The Barrel Rogue 2.0 Exhaust for the Bajaj Pulsar NS400Z is built for riders who want controlled aggression—strong bass, clean flow, and real-world rideability. This isn’t a cosmetic swap. It’s a properly engineered exhaust system designed to complement the NS400Z’s torque-focused engine. Constructed from Stainless Steel 304, the Rogue 2.0 features a precision sub-header with an inbuilt resonator, allowing deeper sound output while maintaining balanced back pressure. The result is a throatier exhaust note with improved throttle response, without the harshness commonly associated with free-flow systems. The system is plug-and-play, requiring no cutting, welding, or modifications. A removable DB killer is included, letting you fine-tune sound levels depending on riding conditions. Designed, developed, and manufactured in India, the Rogue 2.0 reflects Barrel Exhaust’s focus on durability, fitment accuracy, and rider-first tuning. Key Features Designed specifically for Bajaj Pulsar NS400Z Full Stainless Steel 304 construction Inbuilt resonator for controlled exhaust note Deep bass sound with reduced rasp Removable DB killer included Plug-and-play installation Improved throttle response Lifetime rust-free warranty Made in India Product Specifications Material: Stainless Steel 304 Exhaust Weight: ~2.8 kg Clamp Provided: Yes Bend Pipe Included: Yes DB Killer: Yes (removable) What’s in the Box Rogue 2.0 Exhaust Muffler Stainless Steel Sub-header with resonator Mounting clamp & hardware Removable DB killer
