The akra has a more deep resonating tones. that sounds a bit tin-ish to me compared. bro if you can wait till the weekend ill have videos. Doing my dyno tune friday and gonna record the entire thing.Aufitt and HoPMiX, how does this compare to the sound of the carbon fiber Akrapovic slip-on? (video below) The description doesn't indicate if the silencer is installed or not- what do you think? My carbon slip-on will be here shortly, just anxious to get an idea of how it actually sounds under load in a drive-by since all of the other vids on YouTube are at a standstill. Thanks!
