DESCRIPTION

Universal single inlet single outlet electronic valved muffler for custom exhaust fabrication.

 Two material options: 201 or premium 304 stainless steel. Available inlet diameters: 2 inch, 2.5 inch, 2.75 inch, 3 inch, 3.5 inch.

Complete package includes electronic valve actuator, control box, wireless remote and wiring harness. It can switch sound modes with one click, quiet tone for daily commute and deep sporty sound for performance driving. Optimized internal chamber structure balances exhaust flow and backpressure, reducing unwanted cabin resonance.

This weld-on valve muffler requires professional TIG welding installation. The electronic actuator maintains stable operation under high-temperature exhaust conditions. Multiple pipe diameter options fit vehicles of different displacements, while two stainless steel grades meet different budget and durability requirements, widely used for sedan, coupe and performance car custom exhaust builds.

VEHICLE FITMENT

Universal weld-on fitment for most passenger cars and performance vehicles for custom exhaust modification.

Installation Guide & Precautions

1. Mechanical & Welding Safety 

• Professional Installation Required: This is a universal weld-on performance parts. Professional welding (TIG welding highly recommended) and custom piping installation by an experienced exhaust shop are required.
• Clearance Check: Before permanent welding, mock up the muffler under the vehicle to ensure at least 1.5 - 2 inches of clearance from the car body, heat shields, fuel lines, and suspension components to prevent heat damage.
• Flow Direction: Ensure the muffler is oriented in the correct exhaust gas flow direction. Install with the single inlet facing the engine side and the twin outlet facing the rear.

2. Electrical & Wiring Connections 

• Voltage Compatibility: This electronic system is strictly designed for DC 12V automotive electrical systems only. Do not connect to 24V commercial trucks.
  
• Heat & Vibration Protection: Route the actuator wiring harness safely away from high-heat zones (like the exhaust pipes themselves) and moving suspension parts. Secure cables with heat-resistant zip ties.
  
• Waterproof Measures: Although the motor and connectors have basic weather resistance, ensure the control module box is installed in a dry location inside the vehicle (e.g., cabin or trunk) to prevent water ingress.

3. System Testing & Operation

• Pre-Check Before Welding: Connect the control box, wiring, and cigarette lighter/power source before final welding to test if the remote control fully opens and closes the valves smoothly.
  
• Exhaust Gas Seal: Ensure all welded joints are 100% sealed. Any exhaust leaks near the valve mechanism can cause abnormal rattling noises and reduce backpressure efficiency.
  
• Breaking-In Period: It is normal to smell a slight burning odor during the first few miles of driving. This is the protective coating curing inside the new perforated stainless steel baffle core.
  

Trouble-Shooting Guide

1.Valve Not Responding:

• Check if the blue LED indicator on the remote control lights up (replace battery if dim).
• Verify the cigarette lighter power plug or 12V power source is firmly connected and the fuse is intact.

2.Abnormal Rattle or Noise:

• Ensure there is sufficient clearance between the valve actuator motor and the car chassis.
• Check for any pebble or welding slag stuck inside the perforated baffle chamber.

3.Intermittent Signal:

• Do not shield the receiver control box behind heavy metal sheets. Extend the small antenna wire for better wireless reception.

Measurement Confirmation

Measure Before You Buy: Please carefully measure the available space (Length, Width, Height, and Pipe Inlet Diameter) under your specific vehicle before placing an order.
Custom Adjustments: Since this is a universal high-performance baffled muffler, modification shops may need to add extra extension pipes or adjust hanger brackets to fit your unique exhaust layout.
