I just put this ExoticSpeed exhaust on my 370Z 7AT and I love it! I was interested in the Fast Intentions exhaust but didn't want to wait 3 months, this exhaust only took 7 days to get. I bought it from an ebay seller in Canada for $799.99 and $99.99 for shipping. It was listed as being used and refurbished to like new condition, but it actually appears brand new but has a couple very small dents on top of the resonators that you can't see when it is mounted on the car. While cruising at any steady speed from parking lot speeds or at highway speeds it is very quiet, but when accelerating it has a nice low growl. As far as rasp or drone goes, if I listen very closely and try to be very picky, the only time I hear any trace of unpleasant sound is if I accelerate very lightly below 2000rpm with the transmission in D, but it is so minor that I doubt anyone could complain about this exhaust unless they were an absolute perfectionist, or if they wanted a louder exhaust as this one is not loud, it just makes the car sound as good as it looks.
