The blow off valves are more audible with the intake, I personally have them still routed (not VTA) and can easily hear the blow off valve. Many others are reporting the same.My guess would be not, the open air filters make a bit of turbo noise.
In regards to the dyno test, I responded to this test on the other forum linked below. While the dyno test against the Windstorm was done by the competitor who makes the intake, every dyno test with the MDesign was done by enthusiast from across the nation at unbiased and disattached shops. As you can see in the reply to the post, the MDesign intake outperformed the Windstorm/AirRaid intake. We also beat K&N as well, video and information also linked below.
