henschel, as i mentioned if you get the pipe length from the exhaust manifold to where it bolts to cylinder head face and measure around to a total of 13 to 14 inches even you will be very close with the correct length for this system. take note those wrap to center manifolds are not as good for power as the normal 90 degree bend types so to get the length required [ 13 to 14 inches ] alot of the straight section of manifold will be cut off but only do this cutting when you know the pipe is coming on when and where you want it too. once cut thats it. there you go misty you learn something more. lol forgot to mention those props , don,t start off to big for oval , propshop 6719 x 3 is good .
