I have a TC RACING slip-on. He gave me the option of running with the open end cap or using the disc's. I got a lot of low end with the open end cap. Just wondering what I will get in performance wise if I put the disc's on. ANy help would be great.

the disc's allow you i believe to controll the sound level as well as power...adding more discs does something power wise, not sure though....
