Sweet mirror block off plates :lol:
So I've heard that the race kit (K&N, race ECM and pipe) loses a bit of low end on the early XB9's due to the design of the airbox lid... Apparently to regain what's lost all I have to do is swap a lid from an XB12 (better flowing design), but there's 3 fucking different types, 4 if you add the early XB9 :rolf:
