It looks pretty, is about 6 lbs. lighter than the stock piece and it's whisper quiet. Slightly louder at WOT but only slightly. The db killers, there are 2, are welded in place. Not removable, at least not easily removable. I am using it with an Arrow header, it's quieter still on the stock header. This is my 4th KTM/ Akra exhaust combo, by far the least satisfying. Looks great though, questionable performance enhancement. 2/5 stars, would not purchace again.
