I have a flow fx 4x9 muffler that's pretty tame


How long is it? (That's what she said)

These elliptical ("oval") straight-through packed mufflers are all about the same width and height. It's the body length that gives us reference as to how loud it'll be. Generally, the 22" will be like stock, 18" will be a few notches louder (but still mild), the 14" louder still, etc.

That's the characteristics I like about these mufflers. Calm when you want it calm, proportionately loud when appropriate. The scale of volume is determined simply by the length. Although subjective, I believe the sound itself compliments these types of vehicles. Best bang for the buck, IMO.
