I just got a set of these new D-port ram air manifolds from Max Performance and a Pypes Crossflow system installed on our 455. The manifolds are really nice.
The car sounds great and the performance difference from the stock log manifolds and old duals is incredible. I will be posting photos and maybe some video on my Gramma Car thread in the next few days.
Stay tuned!
