I don't think you can deny they are the best bang for the money. They sound fantastic and look good. I think they are the shortest silencers available, and are about 3/4 of an inch shorter than the factory silencers (except for the tip-downs).
I got mine from
Pipe City for $369 which included shipping. A great deal! You may have to email them to order (I did) because these don't show up on their web site.

The biggest down side for me is that the brackets don't fit very well and take some struggle to get right. Mine still aren't straight. It's kind of cheesy the way they work, but a bunch of other manufactures do it the same way.
Also, the Aluminum that they are made out of scratches easily. Something to be aware of.
These are a little bit loud for my tastes, but they sound good.
I recommend them.
