I just ordered the Daytonas to go with my Torq Loopz; as i stated in another thread, the addition of Torq Loopz with stock exhaust added little or no volume (decibels) to the sound of the wing. I'd call it more of a change of tone than a change in loudness. I am not looking for a loud MC so I am hoping the new mufflers don't add too much. I wouldn't mind getting a couple of mpg increase and maybe a little 'attitude' change in the exhaust system. We'll see... will keep you posted but can't work on the bike until house guests leave in a week!
