I ran Alley Kat turn downs for a decade. Best sounding out there to me. They have a deep tone. Not tinney like some.Don't rule out Alley Kats!! If you've never heard their sound; you need to.
Drone and louder exhaust can come with pipes, but the two you mentioned here have several baffle choices for your liking, I have Rush with a custom baffle, but tourqmaster is smaller company and he will work with you on baffle types, but if you want to squeeze it down too much just stay stock and be happy. Mine sounds more like a Porsche when I get on it.Drilled seven 1/2" in each muffler just now. On start up & rev it sounds good...sorta deep. Took it for a ride though and wow...the drone is waaaay too much! Gonna have to plug them up & figure on buying pipes. You folks out there running Rush or Torques have any drone @ highway speeds? Right me I think leaving it stock is going to be the way to go.
