When cruising you can definitely feel the drone in your butt, but it's a good thing .....

If you don't like the loudness their 50 Series has more baffles in them for drone and harshness .... Kinda like the old Hush Thrush mufflers ...
Yup I was waiting to post about the drone - I installed this kit a month ago and love the sound. I do have some drone in the 1800-1900 RPM range however. It seems to be wearing off a little bit as it breaks in. One thing I can confirm - the butt-dyno definitely shows a difference, even more so than when I installed the Airaid. The tips need to be rotated inwards a bit to blend with the contours of the rear valence, and thus the logo is askew but that's ok (unlike the Corsa). It's a great option for the price-point.
