What is up with the disks on the CT pipe? What are they for? Is this a good pipe? Is the horsepower gain really 8 horsepower?

the discs are for tuning the pipe..like say you want more top end, you add more discs (i think.......) and adding more discs makes it louder..so you can tune the pipe to how you want it, power or sound.
