I wanted to know if anyone has increased the diameter of the exhaust and kept the racing beat exhaust. I am planning on doing this and i want to know about the sound change and the effectiveness of this mod and if it is even worth it. Should i have the 2nd cat and the resonator removed or just the resonator or neither?
thanks for any help...
