Has anyone ever installed any of these "stealth exhaust" systems? I know where to get 'em but has anyone used them? Do they work? Do they rob you of any horsepower?

 

Dirtweek did a review in the Nov. issue and said it did work. They tested it on a Vinson and said it didn't lose any top end. It was discribed as an additional muffler that bolts on to your quad. I don't remember how many db's it dropped.
