I did some work on my exhaust and had no idea this is actually what it sounded like on the road. Please excuse the poor audio quality and loud brz cam car, listen with headphones and 720p to get a good idea of the exhaust note.
The exhaust is very low and pretty quiet until it's revved up high. My friend says the note is unique and describes it as "exotic". I can't put my finger on how to describe the sound or a comparison, let me know what you guys think.
