Thrush Glass Pack Muffler

The DYNOMAX Thrush Glass Pack Muffler (Part #24242) is a universal aluminized steel exhaust muffler designed for vehicles requiring compact, effective noise reduction without complex installation. This 25-inch glass pack muffler features a 3-inch center inlet and center outlet configuration, accommodating 20 x 4-inch round body dimensions. Unlike restrictive OEM mufflers, glass pack designs use a simple perforated core wrapped in sound-dampening material, delivering straightforward exhaust flow with measurable noise attenuation suitable for street vehicles, trucks, and specialty applications.

The aluminized steel construction resists corrosion from moisture and road salt exposure while maintaining structural integrity through thermal cycling. At 9.05 pounds, the unit balances durability with manageable weight for suspension geometry. The universal mounting design accepts 3-inch diameter piping, the industry standard for mid-sized engines, eliminating the need for expensive custom fabrication. Real-world users report that glass pack mufflers sustain performance through extended use without carbon buildup restrictions that plague sealed muffler designs, making maintenance straightforward.

This muffler suits enthusiasts building custom exhaust systems, operators maintaining fleet vehicles, and users prioritizing audible exhaust character alongside functional noise control. The 25-inch length and 4-inch body diameter fit most vehicle undercarriage clearances without specialized fabrication or relocation of fuel tanks or suspension components. Glass pack mufflers remain the standard choice when maximum exhaust scavenging and simplicity outweigh OEM-level refinement, making this DYNOMAX unit a reliable, proven component for direct-fit or universal exhaust applications.
