i am thinking about buying the HMF slip on but i was wondering if anyone knows where i can buy one. I was also wondering if the quite core insert takes away from power gains?

thanks

Call and ask about the quiet core. they were supposed to send me a free one..........they forgot to...... :roll:

I don't use the quiet core on mine, but it will kill power almost for sure. It did on my FMF on another quad, and made it feel almost stock.
