what size end cap do you run on a T4 silencer?

I have the largest one. Is that for top end or bottom? Is there a big difference in the performance between the largest and the smallest?

The largest is what comes standard. That produces most top end. I also purchased the smallest for more low end.

for all pipes, this is the rule:
small exhaust tips: more backpressure= more low end, not as much top end

big exhaust tips: less backpressure= less low end, more top end
