For future Google search sake, I have the map kit charge pipes with the vee port pro, it's the same bov used by whoosh's sound symposer setup. It sounds good. It's not a high pitched noise like a tial or dual port would be. Love the full mech straight bov. Feels solid and will no leak. Big bonus with both options, no sound symposer. It helped a lot with an almost echoing from the bolt ons conflicting with the symposer
