Just installed FMF Q Series

Just switched from FMF Powercore 4 SA to FMF Q Series so I will be legal here in Ca. What a difference! I haven't ridden it off-road yet, just took a hot lap around the tract (not really, just a very slow one). But the difference in noise level is astounding!
So far, I also notice a significant difference in very low-end response. Seems snappier. Don't know about top-end, but if it's the only thing legal, doesn't matter at this point. Still much better than stock.
Recommendation is 10-20 hrs between repacks. I suspect this is one reason for conflicting test results. Some of us may not be repacking regularly. My PC-4SA was never repacked and it was getting really loud. I will likely repack every two or three rides or so just to be safe.
Anyway, it's scary. I can actually hear all the sounds coming out of the engine now!

In my case they worked loose, enlarged their holes, and the whole thing came apart. This happened in a race, otherwise I probably would have been able to salvage the thing and fix it, but as it was I got DQed at the next check and the sweep riders could not find the can.
I thought my bike ran great with the Q, in my case it seemed to richen the pilot and idle circuits. It revved out like the stocker, but that midrange hit was softened a little bit.
Hope this helps.
