I had a conversation with Keith about what I liked about the current system, and what I didn't like. He is taking that feedback and increasing the muffler size to accommodate.
Basically, I love the noise when I am on the throttle, at startup, etc. But cruising up a long hill or towing, the noise level is just too high (for my family) at a sustained level.
standard cruising on flat roads is not an issue, but when we travel it becomes a problem. Cant hear the kids in the third row, they complain about the noise, etc.
