I never thought I'd buy an exhaust for a dirt bike, but when FMF had the 20% off sale I picked up the Q4. I wanted to try it and see and without the sale, I may not have gotten it. It's worth it even at regular price. Has a nice tone to it and really woke up the bike with the addition of the JD Jet kit. It's louder than stock, but not so much that it's bad. It seems to have changed the frequency or resonance of sound enough that I don't want ear plugs like I did with the stock muffler. I didn't have a scale, but it feels a little lighter than the stock system as well.
