I have a Koyo TT rad and the Ash 2.5" pipes but they fit so tight that I cannot move the rad up high enough to mount properly with the Mega Z rad guide.
I was told the 1st batch Ash 2.5" pipes did not have the improved curvature that the later batches had in order to fit Koyo and other type rads and thus is the reason why I have the fitment problems that I have.
If someone would like to sell me their Ash rad/fan and/or trade with me my Koyo rad plus cash for their Ash rad/fan, please let me know how much a reasonable offer would be.
Thanks, Tommy
