I have noticed a noise that i believe may be for every GT owner but I'm not fully sure. When i kind of mash the gas or even when i full send, speed is subjective but lower speeds are more noticeable since the exhaust isn't as loud, that i can hear what almost sounds like an exhaust leak from the headers. It sounds like an extremely hollow but muffled exhaust rasp, but from the headers/cats area. The description isn't the best i know, but once you hear it, you can't unhear it.
A few weeks back i had posted about a noise on startup, and this noise is the same as i was describing then but i hear it when I'm driving as well and it's driving me nuts. I did go to my local dealership where they had a GT Premium and i started it just to listen for the noise and i heard it on theirs as well. It has since sold or i would go test drive it and see if it produces the noise I'm hearing.
For any GT owners that may be interested in seeing if this noise is common, remote start your car and listen from under the driver's side door at the exhaust note the car makes on startup, you'll hear it pretty loudly from the catalytic converter area, until idle down and then it goes away, that same noise is produced on my car but on accelerations as well. If you hear the odd noise from under the car at startup, go take a drive with the exhaust open or close, can be heard either way, windows down and music off, and mash it about halfway from a low speed or even a stop, and see if you notice it, again it'll resonate from under the driver's side catalytic converter area. It's easier to hear if you have buildings on either side.
I just find it hard to believe this is a common thing for all of the GTs because it sounds bad, but after hearing the same noise on the GT Premium i started up, I'm starting to think it may be a natural noise the S650 makes. I haven't had anyone drive my S650 with me outside to see how noticeable it is to others, but i can distinctly hear it over the open track exhaust when accelerating so I'm sure it has to be noticeable.
