1. Core Positioning​ A key noise-reduction component of the automotive exhaust system, installed at the end of the exhaust pipe. It weakens engine exhaust noise via a reactive/dissipative composite structure, while guiding exhaust gas to discharge smoothly, reducing vehicle driving noise pollution. Compatible with all fuel and hybrid vehicles.​ 2. Core Functions​ Efficient Noise Reduction: Noise reduction ≥25dB, complying with GB 1495-2002 "Limits and Measurement Methods for External Noise of Accelerating Motor Vehicles";​ Smooth Exhaust: Optimized internal flow channel design, exhaust resistance ＜3kPa, no impact on engine power output;​ Weather & Wear Resistance: Made of 304 stainless steel or cold-rolled steel plate (with high-temperature paint coating), temperature resistance 600-700℃, resistant to rainwater and exhaust corrosion;​ Stable Structure: Welds prevent cracking, vibration resistance (10-2000Hz), avoiding abnormal noise after long-term use.​ 3. Core Advantages​ High Noise-Reduction Efficiency: Composite muffling structure, filtering both medium and low-frequency noise;​ Long Service Life: Corrosion-resistant material, service life ≥4 years/80,000km;​ Easy Installation: Flange/clamp interface, direct OE replacement without modifying the exhaust system;​ Compliant Adaptation: Meets automotive noise emission standards, compatible with National VI, Euro 6d vehicles.​ 4. Adaptability​ Vehicles: Covers fuel/hybrid passenger vehicles (sedans/SUVs), commercial vehicles (light trucks/buses);​ Displacement: Adapts to mainstream 1.0L-3.0L displacement engines, supporting customization of large-displacement (>3.0L) and special-shaped models.​ 5. Service Support​ Contact customer service for adapted vehicle lists and installation dimension drawings; free installation docking guidance provided.
