2 4" aeros will be perfect, 1 6" would be great if you can fit it

two threes only give you 2 sq in over one 4

pie (no not that pie) pie Rsq so 3 " = 1.5x1.5x3.14 = 7.065in^2

the only place i have to put a big port is on the side and i only have space for one. but on top i have enough room for a lot of 3 inch aeros but a 4 wont fit on top
