Ken/Dave,
Any updates on release dates for the new manifold?
I just pulled my tripower off (puts paper bag over face to hide

) to experiment with a Performer/4150 combination and my car
really seems to like it

. With my combo I think it would be even better with an RPM or even a Warrior and your proposed design sounds like the best of both. I was going to look for an RPM on Ebay but will hold out for yours if it won't turn out to be as long a wait as the aluminum tripower

.
