Very nice. The Manley Chinook is supposedly a great bang for the buck. Kevin Deal really likes them. I have never heard it but I trust the opinions of those who have them. You should be very happy with that upgrade
FWIW I'd wait a couple weeks to let the Chinook get broken in before putting the sub(s )in the chain. This will help you identify just how much improvement it did and then enjoy the sub. It should provide another thrill as well
Let us know how you like the upgrades
