Does a glasspack muffler add horsepower?

A glasspack muffler by itself will not directly add horsepower to your vehicle. However, by reducing backpressure in the exhaust system, a glasspack can allow your engine to expel spent gases more easily, which may result in a slight power gain.

The reduced muffling can also create a more aggressive exhaust note. For a significant horsepower increase, more extended engine modifications would be required.

Are glass packs good mufflers?

Glass pack mufflers are good at reducing exhaust noise versus a straight pipe while allowing for freer exhaust flow and a rumbling sound.

They work by passing the exhaust gases through glass wool insulation inside the muffler. The tradeoff is they do not quiet the exhaust as much as a chambered or turbo-style muffler.

How do glasspack mufflers work?

Inside a glasspack muffler are small glass fibers, similar to fiberglass insulation. As hot exhaust gases pass through, the glass wool absorbs and dissipates some sound waves, reducing noise.

The gases flow straight through instead of routed through baffles and chambers like in other mufflers. This straight-through design allows higher exhaust flow for better performance.

Is a glasspack a straight pipe?

No, a glasspack muffler is different from a straight pipe exhaust system. A straight pipe lacks any sound muffling abilities. A glass pack contains an interior chamber filled with glass fibers that provide some level of sound reduction by absorbing noise.
