Prior to buying a catless header, I had some concerns that it would be too loud. Using the free app Decibel X, I recorded the following from normal freeway driving (compare the averages - about 1 dB difference):

While the header has a better note, it's not noticeably louder
(Left is stock, Right is OFH)
Look at the average values (87.9 vs 88.7) - about a 1dB increase. My ear can't tell a difference.
