Sound is a tough sensation to describe in person, let alone with text but we'll give it a go. Many people are now familiar with the chambered "tinny" sound of a Flowmaster; The Hushpower is nothing like this. The sound provided by a Hushpower is a smoother and more refined tone. It is similar to other packed type mufflers, but without the raspy cracks or pops generally associated with these straight through designs.
