We were bored tonight so I convinced the fiance' to do some runs with both her trailblazer and my bonneville next to me in the other vehicle recording it.
Video sound quality isn't the best, but it gives a good idea of the sound. Also you can really tell the difference between a V6 and I6 in these videos. I actually love the sound of both. In person the Trailblazer is louder than the Bonne by a good bit which is hard to tell in the videos.
Turn up your volume and use some headphones if you don't have a good set of speakers!
