2.5" or 3"
Im going to be buying a set of 1 5/8 headmans and the matching y-pipe. I know the y-pipe collector is 2.5" pipe, should I get a 2.5" super turbo or go for the 3" hooker?
The car is a lg4 with 14x3 K&N and will soon have a holley intake and upgraded ignition.

I bet you would see the same 12hp with a 2.5 on a stock 305 TBI as well. Anything is btter than stock that is why you see such a large jump. Dyno the two, one with 2.5 and one with 3 and I bet you would see similar numbers.
