looked under the z today to notice that the hose to my driver side ic (stock) had electrical tape around it. The car was hit on that side by previous owner. After undoing the electrical tape there was a pretty big cut and holes. So i need new hoses but i want to upgrade (hard pipes). only one company showed all the pipes everyone else's just shows the four pipes on top of the motor. do these kits come with all the pipes or just the one in the pics. I could call in the morning, but thought maybe someone might know. Thanks in advanced.
