I have many recordings but they're useless because the mic pics up everything so road, wind and engine noise all blend together. Also the mic doesn't pick up vibrations so no help there.
You will feel and hear none of this in your '15 just as it was not present on my '14. This issue is present solely I believe, on the '17 Mirage CVT's with new programming, redesigned exhaust with no flex joint and stiffer engine mounts.
