FMF Power Core Insert???

Does anyone know if there is an insert that goes into the Power Core system that tones down the noise that a stock FMF pipe makes. I would like a medium between the stock pipe and FMF Pipe.

I checked with FMF about a month ago asking about the same thing. I have a Powercore-4 SQ with Spark Arrestor and the thing is way too loud. I think FMF should give everyone that bought a Powercore 4SQ muffler a free insert as their ads said this system was so much quieter........
