Univ. Magnum Glasspack

The DYNOMAX Univ. Magnum Glasspack is a universal high-performance muffler designed for automotive builders who want an aggressive exhaust tone while maintaining moderate backpressure reduction. This muffler is ideal for street rods, classic trucks, and performance sedans, providing the classic muscle car sound that enthusiasts desire without compromising drivability.

The Magnum Glasspack operates on a straightforward principle: it features perforated inner tubing surrounded by acoustic fiberglass packing, which absorbs high-frequency noise while allowing exhaust gases to flow with minimal restriction. Its larger chambered design maximizes resonance control and maintains scavenging efficiency across mid and high RPM ranges, enhancing overall performance.

This muffler is versatile enough to accommodate most 2.5 to 3-inch tailpipe configurations, making it suitable for retrofit applications. Its 6.36-pound construction emphasizes durability without adding excessive weight, which is crucial for vehicles where fuel economy and handling balance are important. Mechanics and DIY builders will appreciate the straightforward installation process, which can be achieved through welding or clamp-mounting to existing or custom piping.
