I'm running mine (daily) in 5.25 each after displacement (roughly what you are) and I have 4x24 slot ports on each one. 18in deep. Try 5x16 18in deep and don't do an L. You should see impressive gains getting that L out of your port and increases port opening. You might want to tune a bit higher too, Xs love 34-36. You are also running a ton of power for 5.5 cu. tuned to 32. It may be quiet because it isn't cooling properly. I tried running 5k to mine and they hated it. Get much louder on 3k for the both.</p></blockquote><p></p>
