Do these make a significant difference in lowering sound? How is the power difference to you? I've heard the power isn't that different.

IMO more people/manufacturers should run these on 4T's but it will never happen.

It takes the "bark" out of the exhaust note, you can really notice a difference when a bike with a Q4 is on the track vs a stock or aftermarket pipe. I did notice a power decrease, but I'm used to my full-yosh system. It doesn't make it slow by any means and I know people who prefer riding with these pipes.
