Watching on TV it's really hard to pick up just how different every one of these cars sounds, but I thought this video did a decent job. The GTLM 911s scream like
freaking banshees (2nd one is heard around 1:03 in the video, the first is totally drowned out by the Vette), and you can hear them long before and long after they pass. The Vettes and Ford GT are just loud as shit. The Lexus and Mercs have a surprisingly very low pitched note. I thought the M6 had the best all around tone. Notes on the video below:
