Here's how I did mine, when I cut it open I was surprised to see how restricting it was, there is just two 1" holes that pass through the center divider and one of the holes run right up under the inlet of the water box. Do I drilled some extra holes and cut the end of the divider plate of for more flow. It didn't get much louder with the dasa 1200
