Pillows, Cartridges, Blankets – Don’t be fooled by the hype. They do not last longer. They do not attenuate sound better. They do not fill voids and open areas better. Loose Fill is superior in every aspect and takes only a few extra minutes to pack.
Packing Made Simple: As a general guideline:
- The more densely you pack the muffler – the longer it will last, better heat insulation, better performance. But will be slightly heavier and will attenuate sound levels less (increase sound).
- The less densely you pack the muffler – the shorter the life span, less heat insulation, less performance. But will be slightly lighter and will attenuate sound levels more (decrease sound).
