I wonder how much louder it will get after it breaks in. I was thinking about getting either the 18" or 22" just because I know it will get louder in the future.
I wanted the same as you discribed above. trust me, this is your answer!!
No cab drone, no window ratteling exhuast in town. Just a real nice "unstock" (if that makes sence) sound. And it really sounds great when you punch it!!
