Fit was never a problem. Finish is good but Staintune is better.

The seam along the bottom of the Keihans is finished differently, hard to describe, but Staintune looks better there.

Both sets of Keihans developed a small crack in the area where the bracket is. It doesn't seem to affect tune at all, but is a disappointment. They're half the price of the Staintunes, or were. I'd buy 'em again.

I am not claiming a cure all but keeping your front muffler clamps tight really cuts down on cracking there. I check all airheads I work on. It's easy. Reach down and grab the end of the muffler on twist on it. If you can twist it at all, the front clamp needs tightening. I find them loose ALL the time! A loose front clamp lets them vibrate a LOT compared to a tight one.
