Has anyone tried the quiet core insert for the powercore 4? It looks like it's about $25.00 and I was wondering what the TT feedback was.

Awesome! I run it with the spark arrestor screen option. Great throaty sound but still around 96 db! :)

Thanks Indy. I was going to go ahead and get the Q, but really don't want to blow coin on another muffler. I'll do the quiet insert and replace the packing with Q packing.
