I have them on my Road King and like them a lot. Different strokes for diff folks I guess. I like the look of the same diameter for the entire length. I never cared for the "stepped" look of slip-ons. Sound is relative. They are def not as loud as the short shots I had on my Sportster.

Have not have any issues with quality or chrome flaking off.

Here is a video sound clip of mine (I was comparing round end caps and fishtails.. I didnt hear a bit of difference btw)

 

I have them on my street glide and love them they do look small but i like them. My riding buddies saw them first at a bike night i got there early they did talk a lil crap about them looking small till they heard the bike fire up then they wanted to know what they are not 3 of the 4 have them. As far as quality i have had vance and hines on 5 different bikes and never had a problem with chrome flaking off but if i did i the=ink they are warrantied not sure tho.

 

I have the hi output monster ovals and they guys I ride with say they are good riding behind me cause the sound is great. I have had V&H on several bikes and never had any quality issues.

 

My bike had the big radius on it when I bought it and I kept them on for around a year. Just recently changed to pair of POS CFR knock offs. The big radius did have a little bit of "cackle" to them I didn't care for but other than the above mentioned about the small diameter look on a bagger I think they're a good budget true dual setup
