I have the Cobra Speedster Longs installed with the Quietcore baffles, but it is still too loud for me. So I tried wrapping the quietcore baffles with high temp stove gasket rope. It didn't seem to decrease the volume at all, but it did take out the sharp crack to the sound, especially when on the throttle. So that definitely is an improvement. I only covered two of the four rows of holes at each wrapping point. Perhaps I should have covered three of the four. I was thinking about trying the smartpartz baffles next. For any one interested in trying this I used 3/8" gasket, no glues or adhesives, just your standard boy scout rope and knot skills.
