Hell yeah, I have one of those pipes on my little green 78 express. Best thing to happen to expresses in a LONG time.
P.S. One of the I.R.A. guys found out that part of the Iowa restriction is in the intake. I have an extry non Iowa intake laying around if you want it. Might give you a couple more MPH. Also, if you are going to leave it stock, maybe think about slapping a spree head and a uni pod filter on it. Fast expresses RULE!
