It does seem a little more mellow now. Still some cab noise at 1500-2000 rpm. I don't know if it was resetting the computer or the Y pipe that made the difference.

Interesting. That makes me wonder if I really want the Y pipe or not. Because I don't really want my exhaust note to be any more quite or mellow.

Breaking in
Y pipe or
Resetting the computer
