Oh ok I just thought the oil left in the cooler needs to be drained as well.
Im fine without flashing it if it's not gonna be an issue.
I am toying of the idea of putting some aftermarket headers on the Z. Would it still give the Z a little more Hp and noise? Do you still have the OEM headers on Sophie or you upgraded already?
After watching Rolex 24 live in Daytona...the Z all of a sudden sounds so quiet to my ears!!!
