Premium Exhaust Muffler Packing

Crafted from continuous filament fiberglass yarn with ultra-fine glass fiber strands, our high-density packing material is engineered for seamless integration with perforated muffler cores. Optimized for superior noise attenuation and thermal management, this solution enhances exhaust system performance while ensuring compliance with industrial durability standards.


Technical Advantages
Advanced Acoustic Damping
Proprietary fiber alignment disrupts sound wave propagation, achieving up to 30% broadband noise reduction across 500-5000 Hz frequencies.
Extreme Thermal Endurance
Ceramic-enhanced formulation sustains operational integrity at continuous 1200°F (650°C) with <2% mass loss (ASTM E1131 testing protocol).
Vibration-Resistant Matrix
Interlocked fiber architecture prevents packing settlement, maintaining 98% fill density despite sustained exhaust pulsation and mechanical stress.
Chemical Inertness

pH-stable composition resulates acidic condensate (NOx/SOx) and unburned hydrocarbon exposure (per SAE J2748 guidelines).


Installation & Compliance
• Pre-layered fiber bundles enable tool-free core wrapping
• Compatible with OE and aftermarket configurations (2"-6" diameter cores)
• Meets FMVSS 259/SAE J1490 acoustic emission standards

• Zero hazardous air pollutants (CARB/EPA Section 177 compliant)


Cross-Platform Application
Ideal for:
• Automotive/motorcycle OEM assemblies
• High-performance turbo systems
• Marine diesel exhausts
• Off-road/ATV/UTV aftermarket upgrades
