Well today I had the opportunity to see both the Greddy pan & the GTM pan side by side. There is no comparison, the GTM pan is the better way to go. Advantages are, more capacity, no trimming of the sheet metal as it is a direct fit, includes oil pickup tube extension & all hardware to install ( Greddy does not) 1 way baffles keeping oil at the pickup tube instead of Greddys fixed baffles. Deeper heat sink fins for better cooling. Needless to say I bought the GTM pan today
