It definitely had a very deep growl to it now, which I do like. I think it is just the getting use to it being quiet a fair bit as well, more so during idle and light throttle. I imagine it will grow on me, enjoying the lack of drone that was there, but having the deep base exhaust went I get on the throttle. It is surprising how deep is is now, and it was pretty deep before.
